For pure wrongness - A baby seal walks into a club...
For people with longer attention spans -
A duck walks into a bar and hops up onto the stool. It looks at the bartender and asks, "Hey bartender! Got any corn?" The bartender, after recovering from his shock, stammers out "N-no."
The duck asks him "Got corn?" again. The bartender says "No" again.
"Got corn?" "No."
"Got corn?" "No."
"Got corn?" "No!"
"Got corn?" "NO!"
"Got corn?" "NO, and if you ask again, I'll nail your damn beak to the bar!"
The duck pauses to consider this.
"Hey bartender! Got nails?" "NO!" "Got corn?"
