The strangest use for a service bus?

[Wumpty]

What's the strangest use for a service bus you've seen that didn't require any internal/external modifications?

NXWMs Beverley Knight 200was used as a radio studio in June 2012 by Signal 107. Looked very professional and didn't need any modifications!

Any more?

Back in about 1980 I was asked to load the platform of a fleetline with grit,then drive along the 14 bus route while an inspector put a couple of shovel fulls around each bus stop!

I had a bloke stop me to tell me I was losing my load.....I had to explain to him that I was  Gritting......... ;D.
