There is a silly scene in a movie called ‘Liar Liar’ that I used to love as a kid about the importance of not delaying a visit; the underlying plot is that Fletcher (Jim Carrey) is unable to is lie following his son making a birthday wish.

Fletcher: Your honor, would the court be willing to grant me a short bathroom break?

Judge: Can't it wait?

Fletcher: Yes it can. But I've heard that if you hold it you could damage the prostate gland, making it very difficult to get an erection, or even become aroused!

Judge: Is that true?

Fletcher: It has to be!

Judge: In that case I'd better take a quick break myself.
