In the county just north of here, there is a transportation mainly for Senior Citizens called the Monmouth County Senior Citizens Activity Transport.

Sounds like a good idea, but on the busses it says:

MONMOUTH S.C.A.T.

OK, so we have these SCAT busses driging all over the place.

Get the joke? If not...

From http://www.dictionary.com/search?q=scat
From the second entry:

scat Pronunciation Key (skt)
n.
Excrement, especially of an animal; dung.
So, these busses are driving the local dung around?
