When Max first looks into the mirror and sees Leon's (Method Man's) reflection, he says "oh boy", a nod to the line said by Sam Beckett (Scott Bakula) on Quantum Leap (1989), a program where the main character also changes into someone else.
When Max gets home from work and opens his fridge to pick a beverage, he has two options: a beer or a Yoohoo. The Yoohoo is a nod to Adam Sandler's film Big Daddy (1999) when he explains to the kids on the playground "Ya know what's good? Yoohoo with a bit of rum."
The plot involves Adam Sandler's character "becoming" other characters. Ellen Barkin appears in the film. She also starred in another body-swap film called Switch (1991), where she played a womanizing man who is killed and comes back in the body of a woman.
