Remember that time you thought your cat was dying, but it turned out it was only purring? Nope? Haha, we do! Even the cat was thinking, what an idiot. Unless your cat has swallowed a Nokia 3310, when it “vibrates,” it’s purring. Or, is it plotting to kill you? Who knows.
Talking about vibrating. Do you know what else vibrates? Open your mum’s knicker draw and rummage around for a bit. In fact, no, don’t. You won’t be able to look her in the eyes again. We are serious… don’t! Don’t say we didn’t warn you.
