Okay, I'm sure this isn't difficult for most of us, but I imagine it would be for the majority of idiot job applicants. From an actual newspaper (my local paper, in fact) job listing:

PROGRAMMER NEEDED 7777772E 636F6465646A6F622E 636F6D

Personally, I think I'd have not had the introductory unencoded part, in order to find the really curious/geeky ones, but still.
