not that funny
I missed the first 30 minutes so maybe some marvelous character development or story twist happened there. But from the 30 minute mark onwards I didn't really find it all that funny. The funniest part was probably the yoga instructor but that got old. How many times can you watch him dry hump one of the hot wives or wave his b@lls in front of one of the guys?
The only thing that kept me watching was waiting for the next bikini shot of one of the wives. Best was Kristen Bell in my opinion. Loved her bra & panty late night swim.
