Kevin Levin, Ben Tennyson and others in “Birds of a Feather”

(with a smirk as he holds a red object with a curved nozzle) How come you haven't asked me what this is?

I'm worried about the Spidermonkey.

Why?

He saved my life. Yours, too.

I repeat my question.

What's that, Kevin?

See, Ben? That's a normal level of curiosity. It fell off one of those DNAliens. I'm trying to figure out what it does.

Grandpa used something like this to clean his ears. You press down on this and boric acid solution comes… [presses the button and a drop of acid hits the floor]

Ear cleaner, huh?

Guess the DNAliens use stronger acid.
