Watermark

"Why do you watermark every picture you upload?"

"So no one will claim my work as their own."

"But you didn't take any of these pictures! Which work?"

"What do you mean, which work? Pictures don't watermark themselves, you know."

"It's a state of the art harmonica, made according to the latest industry standards."

"Really? What's special about it?"

"It'll give you an electric shock if you play anything copyright protected on it."

Curse

"This one looks ominous." "'Death shall chase on swift wings and prey with talons of fiery bronze upon anyone who dares reproduce in any manner whatsoever the inscriptions of this tomb."

"But first, after this commercial break... The funniest videos found on the Internet!"
