[Eomer of the Rohirrim]

'The Road goes ever on and on'; when that gets stuck in my head I'm singing it all day.

Also archaic words (hither, thither, whence, etc.) On occasions I try to use as many as possible, resulting in mostly annoyed and confused conversation partners. It's a good way to scare off people you don't know very well. Well, that and shouting Be gone, foul dwimmerlaik! (which I sometimes do).
