Crossover fic?

Hi all!

I've been watching all sorts of CM-related clips on youtube and it got me wondering about crossover fics...Can anyone recommend any great CM crossovers (esp humour)? I've read a couple of CM/Big Bang Theory which were great, and would like more of that.

Also, would there by any chance be a story where Hotch or someone on the team watches Dharma & Greg? Because that would make my life complete. Thanks to all in advance!
