This family played one of the funniest (but grossest) pranks on the grandpa of the family! They decided to give him canned cat food to see if he would eat it. They removed a majority of the label from a cat food tin so it only displayed chicken and beef flavor. He caught on rather quickly, but he still went for not only seconds, but thirds before coming to the conclusion that he was actually eating canned chicken and beef cat food. Check it out below!
