This was one of the funniest episodes of CSI I've ever watched. I couldn't stop laughing and I even forgot to pay attention to Warricks case to see if he solved it or not.
There was alot of Greg in this episode and all his scenes were funny, especially when he put the headress on & started dancing out in the hall. The look on Grissoms face was priceless. I couldn't stop laughing. And Greg asking Nick if he wanted a Valium for Sara, that was a great one as well.
The old lady's murder was a hard one to prove with no body, and it was very creative.
Gotta hand it to the writers. Excellent job.
