What a twist!

…but does Adam Adamski have three nipples?

(Actually, this makes strip #44 make a bit more sense; if Adam was the first person, he'd probably be dead by now, and therefore couldn't be Dave.)

(Wait… Poppington said Adam didn't have a last name, but Adam Adamski clearly does. Unless Poppington was wrong about that.)

Don't forget, Poppington was also wrong about the number of nipples Adam was supposed to have!
