Why do Mondays suck?

Why do Mondays suck?
Well, in the old days, when there weren’t many people, God used to make everyone line up single-file every Sunday night.
Then, he’d walk along the line with his Sack Full of Mondays and make everyone pull their Monday out of the bag.
Some were bright and shiny, while others were squelchy and stank like a dead possum.
Over time, the line got too long, and the wait was longer than the rest of the week, so God gave up the practice. Made everyone’s Monday suck.
By the way, Joe, this coffee tastes like dead possum.
