"I bet ye, I can jump out that window and the wind'll bring me back up!" says one drunk.
"Lemme see you do it then!" says the other.
The first drunk walks up to the window, opens it, jumps out and, sure enough, after about 30 seconds he comes floating back up back through the window.
"Pff, whatever you can do, I can do any day!" yells the second drunk, runs up to the window and jumps out. After a few seconds, the sound of him hitting the pavement can be heard.
Spoiler:
when you're drunk."
