400 Calories 

Supposedly making out for 20 minutes burns 400 calories.

Actually, 400 Kilocalories, but food companies thought it would be easier to denote those things we burn as calories, so what the hell. Apparently metric prefixes are fucking scary.

Chad: "Hey Lisa want to burn 400 calories?"
Lisa: "Sure Chad, but I'm not taking off my pants...yet."
{ 20 minutes later }
Chad: "Wanna burn 400 more."
Lisa: "Let's go for 2000. Take off your pants."
