Slapsgiving is a classic. Or it will be =] I definitely plan on watching this episode in the Thanksgivings to come. The previous two episodes involving slaps were awesome and this one did not disappoint. It was absolutely hilarious the entire way through.
Standout moments include: Barney dressing up as Borat the day BEFORE Halloween. The slap song by Marshall.
Ted and Robin baking pies when Ted recalls last thanksgiving when him and Robin had sex seven times. Robin's dating Orville Redanbocker! (sp?)
The actual slap!
and basically everything else. I loved to see Robin and Ted have a talk about their breakup and their friendship and their inside joke. All in all great episode! This show is definitely the new "Friends"!
