Ghost in the milk
We have these glasses at home which have monkeys engraved into them from the inside.
So I was enjoying a glass a milk at dinner. I tipped the glass a little to get a better look at its contents after taking a sip. As the milk ran down the side back into the glass, it contoured the embossed shape. It was supposed to look like a monkey. It looked like this:

Instead of a frollicking simian dangling off the edge of the glass, I get this white, grotesque spook.
Thus, with this event, Halloween was officially kicked off at Gluemeat HQ.
Monkey Ghost!
