Toilet seats

You can't have a toilet seat that is too clean. Nobody would want to use it then.

Bathroom sign

There should only be one bathroom sign, "Don't come in".

Toilet humor

Just toilet humor? The ENTIRE bathroom is a dirty joke.

Multitasking

Reading in the bathroom and being on the bowl is not really multitasking.

Bathroom sounds

Please close the bathroom door. Bathroom sounds should never be heard by the general population.

Age and sitting down

You know you are getting older when sitting down and getting up on the toilet seat is a workout.
