Transcript:
Calvin: Dad, look! The sun's setting and it's only 3 o'clock! Dad: It's not 3 o'clock. Your watch stopped. Calvin: Time doesn't stop ir your watch stops? Dad: Nope. Calvin: Phooey. For a moment there, I thought I'd get rich patenting this thing. Dad: I'd have bought one.
Saying a stopped watch stops time is patently false.
