At least one of them and possibly both (too lazy to Google) used to be on MadTV, which I only know about because occasionally I watched it when I had nothing to do in the 30 minutes before SNL.

Also at least one of them was an occasional recurring character on Reno 911.

(If I sound racist, it's not that, it's that I only recognized one of them while TiVoing over the show's promos and I'm not sure which name is his :-) )
