The film follows estranged friends Harold Lee (Cho) and Kumar Patel (Penn) as they reunite to hunt for a Christmas tree.

Principal photography began later that month and lasted until that August, with filming locations including Detroit, Los Angeles, and New York City.

Kumar, on the other hand, still lives in the messy apartment he once shared with Harold after getting kicked out of medical school due to failing a drug test.

The duo make it out of the building without the Christmas tree and run into their friends, Rosenberg and Goldstein, for the first time in years.

Harold and Kumar plan to steal a tree from a church, but end up participating in a Christmas show featuring Neil Patrick Harris, who they thought had died after being shot outside a Texas whorehouse seven years ago.

The two make their way to Harold's house to put up the tree, but end up being kidnapped by two of Katsov's men, and are saved by Wafflebot.

In exchange for saving his life, Santa agrees to fly them back home in his sleigh, and reveals that he sent the package to reunite the friends.

In April 2009, Kal Penn accepted a position in the Obama administration as associate director of the White House Office of Public Liaison.

"[14] Justin Chang of Variety wrote: "This vulgar romp is a generally harmless, heartwarming affair, a cinematic Christmas cookie almost sweet and flaky enough to cover the fact that it's laced with hash, cocaine and assorted bodily fluids, blood included.

"[15] Kirk Honeycutt of The Hollywood Reporter called it "A mildly diverting naughty comedy, lacking the pure comic nastiness of Bad Santa or the sheer audacity of Up in Smoke.
