Because they're 90 degrees!
Why did the house cross the road, One of the most difficult to solve cross the road jokes, I'll give the answer when you all give.
Your wife back, your dog back, your house back...
You usually want to stand at a corner, they're around 90 degree's
To cut the corners!
Well, it just wouldn't be right.
You go to the corner cause it's always 90 degrees.
Because then they'd be two tired
They warm up singing, 'Mi, mi, mi.... Mi!'
