"Amputee in a bar" joke

A man with no arms walked up to a bar and asked for a beer.
The bartender shoved the foaming glass in front of him.
"Look," said the customer, "I have no arms - would you please hold
the glass up to my mouth?"
"Sure," said the bartender, and he did.
"Now," said the customer, "I wonder if you'd be so kind as to get
my handkerchief out of my pocket and wipe the foam off my mouth."
"Certainly." And it was done.
"If," said the armless man, "you'd reach in my right hand pants
pocket, you'll find the money for the beer."
The bartender got it.
"You've been very kind," said the customer. "Just one thing more.
Where is the men's room?"
"Out the door," said the bartender, "turn left, walk two blocks,
and there's one in a filling station on the corner."
