OK, I have one, but it's a little hard to write down. I'll try anyway-here goes;
There were three girls auditioning to be models. One was a brunette, one was a redhead and one was a blonde. The model agency had decided that it would be a good idea to ask the girls questions about why they wanted the job in the presense of a magic, lie detecting mirror . By using this method, they hoped to find out which one deserved the job the most. If they told a lie, they would be sucked through a magic mirror .The man operating the machine called the girls into the room one at a time.
First, he called the brunette in and asked her to sit next to the mirror.
"Now", he said,"Why do you think this job is right for you?"
The brunette replied;"Well,I think this job is right for me because I'm pretty, patient and very hardworking."
"OK" said the man, "Thank you, you may go now."
He called the redhead into the room and sat her next to the mirror.
"Now", he said,"Why do you think this job is right for you?"
The redhead replied;"Well, I think this job is right for me because I'm good-looking, versatile and incredibly dedicated."
"OK" said the man"Thank you, you may go now."
He called the blonde in and sat her next to the mirror.
"Now" he said "Why do you think this job is right for you?"
"Well" said the blonde"I think..." WHOOOSHHHHHHHH!!
The blonde was sucked through the mirror.
Sorry-I just had to!!

( No offense to any blondes).
