Buddy hanging out while I was brewing:
Buddy: "What's that stuff you're spraying on everything?"
Me: "Sanitizer, but it's cool. It's food grade. You could actually ingest it and be fine, and it doesn't affect the beer's flavor."
Buddy: Squirt, squirt in the mouth..."HACCCHHH, HACCCHHH! Why'd you let me do that???"
Another time...
Buddy: "Is it ok to eat one of these pellets?"
Me: "Yeah, but I wouldn't..."
Buddy: Chomp, chomp "Oh, citrusy and bitter!"
Me: "Good luck with that."
Buddy: "Ahh, that's intense."
Me: "Yep."
Buddy: Later, "Oh, that really stays with you."
Buddy: Next day, "Man, I tried brushing my teeth...didn't really help."
