Cumfy Bus

Can anyone explain to me where these Cumfy Buses have come from? The first time I caught one was very early in the morning over Christmas. They're a different colour to normal buses, have fucking balloons painted on the side, go on insane routes and only seem to charge £1. And there is never, *ever* anyone else on them. Has someone set up their own little bus company to undercut those Arriva wankers?

Who knows!
