Corrected entry: Although the scenes showing poor Andy's erection spitting up urine onto his face when he tries to pee are pretty funny, they're also impossible. When a man gets an erection, a little plug moves into place to block his urethra, since men have only one tube for urine and sperm. Which means a man can't urinate when he's fully erect.

Correction: As a man that has awaken with an erection, I can confirm that it is possible to urinate with a full erection.
