Escaped spider
Look away if you’re not a fan of the creepy crawlies. After the 3D scorpion, we have another insect joker in the house, and this one has thought it through. It’s the addition of the word “aggressive” that gets me, and the thought that I’d walk in, see this and wonder where in the house this aggressive spider was hatching his revenge plan from.
The hole in the side of the cup is even conceivably the right size for a house spider, lending certain credence to the joke. Did he hide around the corner (the husband, not the spider) to watch his wife discover the trap, and then wildly search around for the fugitive?
