Table talk / collusion -- let it slide?

Thanks for your thoughts.

For the rest of the session I protected my cards so darn well that I could barely see them.

They were indeed Muppets, although the wife was out for my blood because I raised her blind a couple times. A few hands later she practically threw her rockets at me after smooth-calling a raise from the small blind with four limpers and check-calling all the way against my TPMK. He seemed like a much better player, but was a bit weak-tight.

I'll be back there, and since they seemed like regulars I'll keep my eyes and ears open and say something if it happens again.
