We used to have a temp from Benson, Arizona who talked constantly about Groovy Greens.
Groovy Greens (according to our temp) is a chain of vegetarian restaurants which is "bigger than McDonald's" in Arizona. One of my coworkers just got back from vacationing there, and she reports that such a restaurant does not exist. There's not a single one, let alone a whole bigger-than-McDonald's chain. The only thing that bothers me more than the fact that somebody would lie about it and then repeat the lie constantly is the way some of my coworkers feel terribly, terribly betrayed by this temp who no longer works for the company. Actually, it doesn't bother me. It amuses me. A lot. Oh, well.
Here's the funniest thing ever. I'm sure you don't think it's that funny, but you also haven't seen The Splu Urtaf Show.
