intern 1: i just biked 4 miles today
intern 2: no way, we've only been here 10 minutes. there's no way you biked 4 miles. are you sure you read the right number?
intern 1: it says miles or km. what's km?
intern 2: kilometers
intern 1: oh, well a kilometer is way longer than a mile, so it must have been 4 miles.
intern 2: yeah. good job!
