I laughed out loud at this. The candy shell on an M&M is 100% accurate.

By the way, I foolishly ignored the many comments about how flat prone the stock tube / tire setup is. Rode 5 miles to my LBS. Got a flat a mile from the store on the way home. The presta tubes I ordered hadn't come in yet, so I didn't have one with me, nor does any shop around here stock them. So, it was a 4 mile walk home across town. It probably looked funny to passers by seeing a 50 year old guy walking a mini velo. I'll be carefully going over the rims for burrs and taping them before installing a new tube and better tires if they ever arrive.
