A man walks into a bar and sits down next to a beautiful blonde.
“I just got this amazing watch,” he tells her, “it can reads alpha waves, and can tell me what a person is thinking.”
“What does it say about me?” asked the blonde.
“It says you want to sleep with me.” said the man.
“Sorry,” said the blonde, “I think your watch is broken.”
“Hmmm,” said the man slowly examining the watch, “It seems to be running an hour fast.”
