For a while now, I've been trying to figure out where catchphrases come from. They're such an interesting phenomenon. The term comes from 1850, according to the Online Etymology Dictionary, and comes from the notion that it's supposed to catch in a person's mind.

On How I Met Your Mother, the character of Barney speaks almost entirely in catch phrases. I wonder if it's supposed to be a commentary on his abject fear of anything approaching real human interaction; a result of his having been abandoned by his father. Or maybe it's a sitcom (sitcom is a term, by the way, coined in TV Guide in 1953 - short for situation comedy.

It's just that, well, my department does include multiple Bobs.
But we also have free pop, free pie, and a Wii in the fitness room. Because I work for that company. Suckas.
