Four or five as a bunch might be a cause for concern… just looking at 'em!

I want to send these down my kitchen sink drain to find where it keeps getting plugged up! I’m sure I’ve got some mini fatbergs going on down there.

I’m guessing use of these is gonna be with anesthetic so you can’t feel it, or at least a sedative so you don’t particularly care that something’s moving inside you.
