Good things to say when someone goes to the bathroom

I always say "Congratulations" or "Good luck." Always have, always will. Sarcastic jerk I am, apparently.

My grandpa always tells me "tell 'em ya know me so you get a good seat."

or "make memories"

"Go with honor."

i always say "Have fun"

"You do realize this is a one way mission. No extraction plan is in place."
