I'm not a guy so it's difficult to imagine what a guy's restroom looks like - I assume it's alot like the ladies' one but with urinals....

This still made me laugh however, esp;

If you happen to fart during urination, do not look around to see if anybody heard it. Chances are they already know it was you, and chances are, they’ve done it too. Just pretend like it didn’t happen and go about your business.

and

When you shake it off, make sure drops of urine do NOT get all over you or the floor. It’s a bad idea to shake wildly, due to the mystery of where it will land.

Yes, it's immature but it is also very funny ^_^
