Tom arguing with inanimate objects that have a weird power over him (Abba Box, Squeaky toy, cell phone, etc)
Tom bragging about being awesome at something even though he's never done it before.
Obsession with mustaches.
I also like all the weird shibboleths that sort of organically spread, like Enguhland, Barnes & Nobles, and all the words where long vowels are replaced w/short ones or vice versa, as in coongas & shon't.
