Lily cringes for her friend while Barney says, "I'm missing my wisdom teeth. Outpatient procedure. Local anesthesia. Whatever. It ain't a thing." Ted thinks they should go out in the alley with Doug. Lily tries to talk sense into him, reminding him that he's thirty.

Saget!Ted narrates a series of flashbacks to show us the extent of his experience in physical altercations. He was punched once at a club, when there'd been a big misunderstanding. (I can't identify the clip -- is it continuity, like from Okay Awesome or something, or simply retcon?) As a college-aged Camp Counselor, Ted was punched in the nuts by a little kid. Saget!Ted adds, "In college, I studied some kung fu." We flash back to Ted and Marshall's dorm room. They're sharing a really big sandwich and watching a terrible martial arts flick. Saget!Ted tells us there was some other stuff, and we see Ted dueling with Marshall, reuniting with Punchy, and teasing us big time, by which I mean we see a shot of The GOAT! while Saget Ted says, "The thing with the goat wasn't for another few months." Mean. For all that, though, Ted has never been in a fight, but that's about to change. Current day Ted announces to the gang that he's going "out there."

Lily and Marshall try to talk him out of it. Marshall confesses he's been in plenty of fights; he's not proud of it. Ted doesn't buy it. When Marshall says he fought with his brothers, Robin and Ted laugh. Barney joins them. "Yes, I'm sure there was quite a rumble in the Eriksen rumpus room." We're treated to a scene of the mental picture this gives the gang, with one of Marshall's brothers praising brotherly horseplay as Marshall takes the role of the Tickle Monster, and another Eriksen boy gives Marshall noogies. This continues until Marshall calls "Timesies" and they stop for a cocoa break. Back at the bar, Marshall and Barney slurp their drinks as if it's hot chocolate, and Marshall shrugs them off.

Ted declares it's clobbering time. When he starts to leave the table, Lily tries to stop him by pointing out that being a nice guy is his best quality. Ted's tone grows serious. "Is it? Because I seem to remember this nice guy getting dumped by his fiancée for a Taekwondo instructor. Look, this may sound crazy... but I think this is an experience I need to have."
