A couple of my pathetic jokes have turned up in commercials recently. They aren't all that original or clever, but it still ruins the fun for me. The one I keep seeing features some pigeons, and one of them tells the others to "fire at will", which gets the response "how did you know his name was Will?", and later "it's Will! Hi, Will.", and the first winged rat says "his name isn't Will!". Or something like that. I usually go with something like "what did Will do?", or when watching ST, especially TNG, "and then you will blow up your own ship...fire at the bad guys!". Yeah, Picard can be stupid sometimes.
I forgot the other joke/commercial. I will be back if I see it again.
