MonkeyBoy, I searched on "bad date jokes" and came up with this. I'm sure one of these will work. LMAO
55 WAYS TO GET RID OF BLIND DATES
1. At dinner, guard your plate with fork and steak knife, so as
to give the impression that you'll stab anyone, including the
waiter, who reaches for it.
2. Collect the salt shakers from all of the tables in the
restaurant, and balance them in a tower on your table.
3. Wipe your nose on your date's sleeve. Twice.
4. Make funny faces at other patrons, then sneer at their reactions.
5. Repeat every third third word you say say.
6. Give your claim to fame as being voted "Most Festerous" for
your high school yearbook.
7. Read a newspaper or book during the meal. Ignore your date.
8. Stare at your date's neck, and grind your teeth audibly.

what they are talking about.
10. Stand up every five minutes, circle your table with your arms
outstretched, and make airplane sounds.
11. Order a bucket of lard.
12. Ask for crayons to color the placemat. This works very well
in fancier venues that use linen tablecloths.

begins talking about themselves.

plate than they do.

20. Chew with your mouth open, talk with your mouth full and
spray crumbs.
21. Eat everything on your plate within 30 seconds of it being
placed in front of you.
22. Excuse yourself to use the restroom. Go back to the head
waiter/hostess and ask for another table in a different
part of the restaurant. Order another meal. When your date
finally finds you, ask him/her "What in the hell took you so
long in the restroom?!?"
23. Recite graphic limericks to the people at the table next to you.
24. Ask the people at the neighboring table for food from their
plates.
25. Beg your date to tattoo your name on their derriere. Keep
bringing the subject up.
26. Ask your date how much money they have with them.
27. Order for your date. Order something nasty.
28. Communicate in mime the entire evening.
29. Upon entering the restaurant, ask for a seat away from the
windows, where you have a you have a good view of all exits,
and where you can keep your back to the wall. Act nervous.
30. Lick your plate. Offer to lick theirs.
31. Hum. Loudly. In monotone.

pepper shakers, silverware, floral arrangements... i.e
anything on the table that isn't bolted down.
33. Hold a debate. Take both sides.
34. Undress your date verbally. Use a bullhorn.
35. Auction your date off for silverware.
36. Slide under the table. Take your plate with you.
37. Order a baked potato for a side dish. When the waiter brings
your food, hide the potato, wait a few minutes, and ask the
waiter for the potato you "never got". When the waiter
returns with another potato for you, have the first one back
up on the plate. Repeat later in the meal.
38. Order beef tongue. Make lewd comparisons or comments.
39. Get your date drunk. Talk about their philosophy. Get it on tape,
and use good judgement in editing to twist their words around.
40. Discuss boils and lesions, as if from personal experience.
41. Speak in pig latin throughout the meal (Or ubber-dubber
language, or just nonsense).
42. Take a break, and go into the restroom. When you return to the
table, throw a spare pair of underwear on the back of one
of the chairs. Insist that they just need airing out.
43. If they are paying, order the most expensive thing on the
menu. Take one bite.
44. Bring 20 or so candles with you, and during the meal get up
and arrange them around the table in a circle. Chant.
45. Save the bones from your meal, and explain that you're taking
them home to your invalid, senile old mother, because it's a
lot cheaper than actually feeding her.
46. Order your food by colors and textures. Sculpt.
47. Take a thermos along, and hide it under the table. Order
coffee, and fill the thermos one cup at a time, taking advantage
of the free refills.

a simliar vein, insist that he take a bite of everything on
the plate, to make sure no one poisoned it.
49. Accuse your date of espionage.
50. Make odd allusions to dangerous religious cults.

pay the bill.

54. Feed imaginary friends, or toy dolls you've brought along.
55. Bring a bucket along. Explain that you frequently get ill.
I guess I could pretend I have an invisible friend and talk to my invisible friend. That might make him think I'm nuts and he might get the hint.
Then again, he might be just as nuts and might think I'm intriguing.
Works for me too.
