Fred insists to his friend that he has a hyper intelligent dog that can talk. Sceptical, the friend enquires of the dog "What's 2+2?"
"Five" says the dog
"Holy shit a talking dog!" says the friend "This is the most incredible thing that I've ever seen in my life".
"What's 3+3?"
"Eight" says the dog.
"What is this bullshit you're trying to sell me Fred?"
