In what episode does Marshall say (while in Maclaren's trying to act "natural") "Guys, I don't know what to do with my hands"

Im pretty sure its season 3 episode 14 "the bracket" where they try to find oot which girl is sabotaging barneys lovelife!?

robin comes up with a plan to make the girl warn her aboot barney at mclarens so we see the whole thing play oot with robin doing a voice over.
