When they run into Neil Patrick Harris at White Castle, he reveals Harold's car is just outside, and says he'll buy them breakfast.
Harold: Do you realize what the hell we had to go through after you took the car?! NPH: ... Yeah. It was a dick move on my part. That's why I'm paying for your meal. [under his breath] Prick.
After giving money for the burgers, NPH also gives $200 for Harold's car.
Harold: What happened to my car?!
NPH: I made some love stains in the back...
(everybody stares at Neil in awkward silence)
NPH: You'll see.
While running from Princeton University security, Harold and Kumar notice Cindy Kim's party isn't so lame after all, and they almost wish they'd stayed.
As Kumar buys weed from the Princeton University, which ends up costing $80.
Kumar: What kind of a hippie are you?
Hippie: What kind of hippie am I? Man, I'm a business hippie, I understand the concept of supply and demand.
Kumar tells Harold they should take the hang-glider to escape the cops, saying he used to hang-glide with his father. But just when they're about to hang-glide, Kumar tells him he hasn't really hang-glided before. After crash-landing, Harold strangles Kumar.
