7.2/10. A perfectly fun Kill Bill homage (which is itself a pastiche -- we're through the looking glass here people). I remember some controversy about the gang dressing up in Asian garb for the "training" scenes, but I think it's in the spirit of kung fu movies the show is imitating here. Like I said the last time we did one of these, I'm pretty tired of the slap bet business, and frankly I think it should have been a one hit wonder, or at least something brought out to punctuate an episode like it was with Barney's one-man show than building entire episode around it.
Still, it was a fun entree into seeing Marshall go all Enter the Dragon. There was a lot of physical humor here, between the rapid-fire slaps and the slapping tree and the slow motion (poorly green screened) slaps. There was also a lot of the usual slap-related word play. It was fairly enjoyable, even if it's more of the broad humor and empty calories the show seems to have given into at this point. It was nice to have the angle that Barney had become inoculated against the fear of the slap, and then the kung fu story restored his anxiety, only for them to treat it very matter of factly afterward.
The Boys II Men appearance was pretty superfluous, but there's a bit of a pointless guest star-palooza going on this season anyway. This all makes me sound pretty down on an episode that I mostly enjoyed. It was basically cotton candy -- perfectly nice but pretty empty after the fact.
