Friday Joke- Hi-tech

A guy walks into a bar and sits down. He starts dialing numbers, like a cell phone, on his hand, then talks into his palm. The Bartender walks over and tells him this is a very tough neighborhood and he doesn't need any trouble.
The guy says, "You don't understand. I'm very hi-tech. I had a phone installed in my hand because I was tired of carrying a cellular." 
The bartender says, "Yeah? Prove it!"
The guy dials up a number and offers his hand to the bartender. The bartender talks into the hand and carried on a conversation.
"That's incredible," says the bartender, "I would never have believed it!"
"Yeah," said the guy, "I can keep in touch with my broker, my family, you name it. By the way, where is the men's room?" The bartender directs him to the men's room still in awe.
The guy goes in and 5... 10... 20 minutes go by and he doesn't return.
Fearing the worst given the neighborhood, the bartender goes into the men's room. There the guy is spread-eagled against the wall. His pants are pulled down and he has a roll of toilet paper up his ass.
"Oh, my!" exclaims the bartender, "Did they rob you? Are you hurt?"
The guy turns to him and says, "No, I'm fine. I'm just waiting for a fax!"
