Enroute from SEA to BZN, last flight out. I'm flying with an older captain, one of those guys who just doesnt care anymore, but in a funny way we're about 15 miles east of seattle when we get the call from SEA Center

"Horizon XXX proceed direct FEBUS, direct BZN"

Captain replies: "Uhhhhhhh, say again...direct Beavis, like Beavis & Butthead?"

Seattle replies: "Horizon XXX, negative...Foxtrot, Echo, Bravo, Uniform, Sierra"

Needless to say, i was dying...i wanted to make a PA to the passengers saying "Point of interest, off to the left you can see Beavis from Beavis & Butthead"
