An old one:
When the usher noticed a man stretched across three seats in a movie theatre, he walked over and whispered, “I’m sorry, sir, but you’re allowed only a single seat.” The man moaned, but did not budge. “Sir,” the user said more loudly, “if you don’t move, I’ll have to call a manager.” The man moaned again but stayed where he was. The usher left, and returned with the manager, who, after several more attempts at dislodging the fellow, called the police.
The cop took a look at the reclining man and said, “All right, boyo, what’s your name?”
“Samuel,” he mumbled.
“And where’re you from, Sam?”
In all things in life: stop, think, observe, plan.
