Downtown, Lemon and Jenna have procured the magical janitor key to Duffbucks and are ready for a showdown, possibly including knives. Dennis entirely too quickly jumps to the conclusion that they want him to rank them. Lemon scuttles that idea and gets to the point: Dennis is an unimportant a-hole. Then he reveals that he had sex with Jenna in her bed. Though angered by the defilement of her snacking station, Lemon decides to take the high road. Dennis stoops to rank them, putting "Blondie" at #1 in retaliation. Lemon continues out. Jenna does the Jenna thing and laps up any praise, regardless of how insulting and transparent.

Uptown at Jack's birthday party, Adam West makes an introductory speech in Batman mode, then flubs and calls the man of the hour "Jake Dellahee." It does nothing to help Jack's waning joie de vivre. He dismisses the guests. Adam West exits, muttering about his contractually stipulated free meal. Commercials.

When we return, Lemon has arrived fashionably late to the party to find no one but Jake Dellahee mournfully viewing his childhood birthday party on a loop. He wonders what was in the box that made him so happy. He wants that feeling back -- literally. He vows to find out what was in the box and buy it again, no matter the cost. Alternately, he will "Benjamin Button" himself. "We're not meeting in the middle!" Lemon shoots back.

She returns to work to find Pete in the midst of space-ifying 30 Rock. He has devised a pitch-perfect ruse to make Tracy think he's at Cape Canaveral. Some of the particulars: a blindfold, NBC New York's traffic chopper, Dot Com brandishing a heat lamp, and Kenneth using a Bonzi Buddy-like computer program to order Tracy to do "space sit-ups." Tracy asks the computer when he'll "get some Tang," then adds, "Also, I'm thirsty." Word play!

Lemon walks into the studio to find Jenna in full Peter Pan regalia, already strapped into her harness. Jenna admits she was totally satisfied by the Dennis showdown. She fist bumps Lemon for sisterhood and heads up into the air. Lemon is less keyed-up on female bonding, though, and decides not to speak up when she notices Jenna's harness clasp isn't securely fastened. Down falls Jenna. Lemon belatedly warns Jenna to be careful, then runs off.
