Anyone have a good source for cartoon orchestra type samples?

You know: Raymond Scott, Popeye, type things with lots of trumpet mutes, t-bones with hats & plungers, bass clarinet key clicks, temple blocks, et al.

I guess I have a lot of this stuff from regular orchestral libs, but I was thinking that a lot of it sounds too 'straight' and was wondering if anyone had already done this since it -was- used so much in scoring.
