Buddy: Is that a UFO on your shirt?
You: It's a brake disc and caliper.
Buddy: Why is it falling down?
You: It's not falling, it's hot.
Buddy: Why is it hot?
You: From braking.
Buddy: Why are you wearing a shirt with a giant brake on it?
You: Why are you wearing a shirt with a tiny dude on a horse holding a mallet?
