A joke from Just a Robot's video "Why are Caillou Gets Grounded videos a thing?"

Robot1: Why am I seeing all these GoAnimate videos?

Rule 34P

If a dog exists you can find him on the internet and pet him if you look long enough

Alice: Aaawww all these dogs are so cute! I wish i could pet them all!
Bob: Rule 34P, you definitely can, but you have to be prepared and at full petting capacity, otherwise you'll overdose on cuteness!
Alice: Totally worth it! I would rather die from too much petting than without it!
