Ed Helms:
PK: I kind of pieced together the entire weekend, or night, except for the chicken.
EH. The chicken is the Great McGuffin of "The Hangover." It's never explained. But, you know the only reason it's there is because...I mean there is no rational explanation for it. Although Todd will tell you, Todd Phillips the director, when I called him on the chicken I was like, "What's the deal with the chicken?" He says that we stole the chicken to feed the tiger.
PK: That's what I thought.
EH: But I don't know where we got the chicken.
PK: It's either that or the baby. To feed the tiger, I mean.
