OK, that episode was stupid as hell but it was pretty funny. It made me laugh. It was nice to see something a little different to break up the monotony of this season so far.
Pretty much it.. it was a nice standalone episode and i loved the digs at all the cheap Kung Fu movies.
I also laughed quite a bit when everybody else always backed up Marshall with his insane, Barney level stories
Slap Bet is one of my all time favorite episode though many slaps didn't live up to the running gag. The best one is Marshall knocking the shit out of Barney when he performed his ludicrous play to get back at Lily.. the slap came out of nowhere which made it so funny.
I just hope the final slap will become truly legendary (and no.. i will not wait for it).
