Mexican Spaceship 

What some workers on a jobsite call the portable toilets (Port-a-Lav, Port-a-John, PortaPotty or what ever company name they go by in your region)

Overheard on a jobsite...Hey, look at those guys coming out of the Mexican Spaceship with their hard hat on...they look like astronauts of some sort...besides, who wears a hard hat to the toilet anyway?

Mexican Spaceship 

Construction site bathroom, also known as a "blue house" or port-a-john.

The laborer had too many tacos the nite before so he relieved himself in the Mexican Spaceship.
