A guy walks into a bar and orders a whiskey.
Just before he takes a sip of his whiskey, a guy runs in and says:
“Bill, your house burnt down!”
So he runs outside, but then he thinks:
“I don’t have a house,”
So he goes back into the bar and takes a sip of his whiskey.
Another guy runs in and says:
“Bill! Your dad died!”
He runs out of the bar, gets on his horse and rides a little ways, but then thinks:
“I don’t have a dad,”
So he goes back into the bar and drinks almost all of his whiskey.
Then another guy runs in and says:
“Bill! You won the lottery!”
So he runs out, gets on his horse and rides all the way to the bank, but then he thinks:
“My name’s not Bill.”
