I like to give credit when I find crap on X, but it makes you click over to there to see the whole post, so here it is.
A US Air Force B-52 is being escorted by a flight of F-16s...One of the F-16 pilots is a showoff, and says to the B-52 pilot, "bet you can't do this," as he puts his plane into a snap roll.
The B-52 pilot says, "Nope, can't do that."
The F-16 pilot then says, "bet you can't do this" as he does an inside loop.
The bomber pilot replies, "Nope, sure can't."
The F-16 pilot is feeling pretty cocky when the Bomber pilot says over the radio, "Bet you can't do this."
After several minutes, nothing has happened. The B-52 is still flying straight and level. "Well?" The F-16 pilot asks.
The B-52 pilot replies, "I just went to the can, took a leak, got a cup of coffee, then shut off 2 engines."
