I secretly cringed after that time we were in Berlin and I told that terrible "Have you guys... SEEN KYLE??! (He's about this tall.)" joke.
(For those that don't know it, you extend your right arm out, palm down, horizontally, while saying the last part loudly.)
It wasn't until after I'd said it that a) I realized that it was totally and absolutely illegal to tell there and b) that I was calling attention to the height of someone named Kyle.
Herpity derp.
