Penny pořádá Halloweenskou párty, na kterou jsou pozváni všichni čtyři fyzikové. Stane se však, že se všichni převléknou za Flashe, a tak nastane čas pro záložní kostýmy. Na párty se dostaví už pět minut po začátku, za což u Penny nesklidí velký úspěch. Na párty poté snaží seznámit s Pennyinými příteli, ale moc jim to nejde a nepomáhá jim v tom ani Sheldon, který se všem snaží vysvětlovat, že je skutečně převlečen za Dopplerův jev. Poté dojde k menšímu konfliktu Leonarda s Pennyiným expřítelem, kvůli němuž Leonard a Sheldon raději párty opustí. Když ráno po akci hledají Rajesje, vyjde najevo, že na párty i přes jeho neschopnost mluvit s opačným pohlavím sbalil holku a vyspal se s ní.

The guys are invited to Penny's Halloween party, first turning it down as they don't dance but changing their mind when costumes are mentioned. At the party, the guys have problems socializing; for example, Sheldon is unable to explain his costume as the Doppler effect since none of Penny's friends are physicist or smart enough to understand his explanation, Raj cannot speak to women, and Howard is mistaken for Peter Pan instead of Robin Hood, and Leonard is insecure. Later, Penny's ex-boyfriend Kurt (Brian Wade) shows up and confronts Leonard, causing him to leave.

Later that night, Penny goes to check on him and apologizes while also very upset about Kurt. Leonard tells her that she is perfect and she kisses him. Leonard asks her how much she has had to drink, she claims "a lot" and that he was smart for figuring that out. Leonard sarcastically admits "yea, I'm a fricking genius" for stopping Penny's advances. She goes back to the party kissing him again in front of Kurt, promting Leonard to say "That's how we roll at the Shire!", before locking the doors in panic. Meanwhile, Howard cannot find Raj, who ends up going home and has sex with a woman he had met at the party, who found him to be a "good listener".

Recurring character: Brian Wade as Kurt
Title reference: Leonard's Halloween costume; he dressed up as Frodo Baggins from The Lord of the Rings.
