"Hello Micheal. You are probably wondering why you're here. I wanna play a game. Your whole life you've neglected your calves by getting your driver's license at 16 and not participating in school sports. The house you are in is set up with a full gym. A 6 month supply of oats, powdered milk, rice , canned chicken and broccoli. you will have 6 months to increase your calves by 1.5 in before I flood this house with Monster Energy, Zero Ultra™. And you might want to hurry because I've locked Rich Pianna in the basement with a recording of you only using one scoop for a 10min workout on an elliptical machine on a loop. The basement will unlock in 5 months. Good luck."
