Sex is like Maths

My homework seems to have multiplied over the weekend. I did not have this much on Friday. Why, oh why did I have to work 9-6?

Now I'm exhausted and I honestly just want to curl up with a "Cheer Up Hedgehog-"Hedgehog.

This makes me smile:

sex is like math: you add the bed, subtract the clothes, divide the legs and pray you don't multiply."
