Caleb is can imitate any act he's seen, and he's seen an awful lot of them. He's actually got talent to back up his ego. The problem is that this only really gets mentioned on his characters page since very few good acts work well in the comic strip format.
This was Caleb's motivation for getting Peter and Brisbane to perform as a duo. I hope that I made it obvious in both introductions, but he's serious about what he does.
Was this a reference to Caleb not believing in the outside world? I think so - I hadn't completely dropped that idea, but I thought I was trying to downplay it a bit at that point.
"Did you guys see my sandwich?"
"You see one sandwich, you've seen them all".
Yes, I'm quoting my own dialogue. I'm allowed to do that, and I really like that exchange.
I like this comic. A lot.
