The scene in question occurs roughly twenty minutes into Hot Rod. Rod Kimble, played by Andy Samberg, sits inside a rusted Chevrolet cargo van with his ragtag stunt crew. They are planning a massive jump to raise $50,000 for a heart operation for Rod’s abusive stepfather, Frank, played with deadpan ferocity by Ian McShane. Before outlining the logistics, Rod attempts to rally team morale through an absurd ritual of personal introductions.
Samberg stares ahead, serious and dead-eyed, uttering the line: "Hi, my name is Rod, and I like to party."
What follows is an unbroken sequence of competitive escalation. His stepbrother Kevin, played by Jorma Taccone, immediately mirrors him: "Hi, I'm Kevin, and I like to party."
Samberg cuts him down without hesitation: "Uh, no, Kevin, I know for a fact you don't party. Okay, nobody parties but me."
Enter Dave, played by Bill Hader, leaning forward through the front seats: "Sweet, so looks like we're all here. Hey, my name's Dave, and I like to party."
Samberg's frustration boils: "No, Dave, that's what I said. Dave, you don't party."
Finally, Danny McBride's character, Rico, pops into the frame with absolute conviction: "Hey, what's up, I'm Rico, and I like to party."
"No, Rico! I'm the only one who parties!" Samberg screams, slamming his hands against the interior trim.
The rhythm of the dialogue relies on repetition, territorial insecurity, and an entirely undefined definition of what it means to "party." Nowhere in the shooting script, written by Pam Brady, nor in the improvised takes captured by director Akiva Schaffer, does anyone say the name Bobby.
