"A Very Special Bar" joke

This guy goes up to a bar located at the top of the Empire State Building in New
York. It looks like a nice place and he takes a seat at the bar next to another
guy.
"This is a nice place, I've never been here", the first guy says.
"Oh really?", the other replies, "it's also a very special bar."
"Why is that?", the first guy asks.
"Well, you see that painting on the far wall? That's an original Van Gogh, and
this stool I'm sitting on was on the Titanic."
"Gee, that's amazing!", the first guy says.
"Not only that, but you see that window over there, fourth from the right? Well,
the wind does strange things outside that window. If you jump out you'll fall
about 50 feet before the wind catches you and you're pushed back up."
"No way, that's impossible", the first guy replies.
"Not at all, take a look", the other man replies and walks over to the window,
followed closely by the first man. He opens the window, climbs over the sill and
falls out. He drops 10...20...30...40....50 feet, comes to a stop, and whoosh!
He comes right back up and sails back through the window.
"See, it's fun. You should try it", he says.
"Try it, I don't even believe I saw it!", the first man shouts.
"It's easy. Watch, I'll do it again". And with that, he falls out the window
again. He drops 10...20...30...40...50 feet, comes to a stop, and whoosh!
He comes right back up and sails back through the window.
"Give it a try, it's a blast", he says.
"Well, what the heck, I'll give it a try", the first man says and proceeds to
fall out the window. He falls 10...20...30...40...50...60...70...80...90..100
feet and splat!
He ends up as road pizza on the sidewalk. After watching the first man fall to
his death, the other guy casually closes the window and heads back to the bar
and orders another drink. The bartender arrives with the drink and says, "You
know Superman, you're a real jerk when you're drunk".
