Well, he didn't get angry until he waved it over the table, so it makes even more sense!

Fun Fact: Cattle can't see red. They'd charge at a flowing cape even if it was yellow, blue or even yellow (Matador Mario anyone?). So what's the red cape for? 1. To mask the blood. 2. It's the movement of the cape that causes the bull to charge.

Doesn't make this picture any less funny, though!
