I LOVE "Seinfeld".... I once saw the woman who played Jason Alexander's mother on the show say that one time during a taping of one of the episodes, Jason Alexander ad-libbed, and she and the entire studio audience laughed for literally a half hour before they could pull themselves together to finish taping the episode

So now when I see that particular episode, I crack up, knowing what was behind the filming of it. lol
Here's the episode:
"George's" mother finds George "treating his body like it was an amusement park!". She somehow falls down or something and ends up in the hospital in traction. He goes to visit her, and while he's there, the woman in the next bed is having a sponge bath by the nurse. They are behind a curtain so you only see their silouettes... But he hears them too, as the nurse undresses the woman and the woman verbally is enjoying the sponge bath...(its all very innocent, but George's imagination is getting the best of him! LOL)...
George's mother starts to say she's hungry and she doesn't like the hospital food, so she asks George to go get her a sandwich...pastrami, I think....lol.... But George does NOT want to leave because he's enjoying hearing the sponge bath too much....lol.... so as his mother begins to whine, saying "Georrrrggge...I'm hungry nowwwwww...." (and here is the ad-lib), he distractedly sticks his hand into his pants pocket, all the while not taking his eyes off the curtain, and tosses a pack of Tic Tacs at her and says "here! have a tic tac!!".
ROFL!
Not sure if this is translating well, or if I did a good job explaining it, but if you've ever seen this episode, its a very funny scene!
