Guess Who is a 2005 American romantic comedy film directed by Kevin Rodney Sullivan.

Theresa Jones takes her boyfriend, Simon Green, to her parents' home to meet them on their 25th wedding anniversary, planning to reveal that the couple are engaged.

Percy also happens to stumble on Simon jokingly wearing Theresa's lingerie while the couple is playing around in her childhood bedroom.

Reggie manages to convince Simon to reveal that he lied about being a NASCAR pit crew member and also that he needs a $50,000 loan.

Furious that he did not tell her the truth, Theresa leaves while Percy's spying and plagiarism of his vows temporarily strains his relationship with his wife, Marilyn.

USA Today said of the film, "A succession of tired race jokes made worse by the bad comedic timing of the bland, under-talented Ashton Kutcher", The Wall Street Journal said, "Guess Who is, impurely and simply, a comic premise borrowed, turned around and dumbed down to the level of sketch or sub-sketch humour" and Rolling Stone said, "Guess what?
