Any size hot dog can be a bun-length hot dog when you spiral-cut them! Instructables member dreamberry shows us how, using a drill bit and a knife. Commenters suggested using a bamboo skewer instead of a drill bit, so you can boil, grill, or deep-fry the dog in no time. Link -via Laughing Squid

PS: Once you master the technique, you'll want to try the double-spiral cut. Link
