The Granddaddy WTFbus of Them All (WTFbus installment #5)

[Kitsa]

I forgot the best thing about this WTF bus...instead of the "rrrrr" of the traction sound that's common with these, this one combines it with a bell. So you have a background rrrrrrr, but when you push it, it emits a muted *thump* DING *thump* DING *thump* DING.
