Person#1: So I was at the Quik Stop getting a pack of smokes and I was totally getting the stink eye from some Treadmill Gerbil in under armor wear, probably because I was wearing my yoga pants, yanno the ones that my mom got me? The really comfy ones. And my reeboks.

Person#2: Ugh, I hate those people. I don't think they even know how to run off of a treadmill.

Person#1: Yeah...running down a street around a block might cause them to have a conniption, they'd probably stand on their front stoop wondering where the "start" button is.
