Homer and Bob go to Moe's Tavern, where the assailant fires at Homer with a gun, before escaping in a tow truck. Bob suggests that Homer should stay home and out of sight to be safe, but the latter is named the King of the Springfield Mardi Gras, in which he must ride on a float for the whole day. Bob discovers that Homer won because someone rigged the ballot in his favour, but Homer takes part in the parade anyway in hopes of luring out his attempted killer. At the parade, Bob learns that a brake line on Homer's float has been cut, and draws a correlation between the wrench used to lock Homer in the steam room, the wrenches in the tow truck and a smudge on the spa invitation, realizing that Junior is the killer. As the float goes out of control, Bob saves Homer by getting fired out of a cannon and grabbing Homer with his huge feet from above, just before the float crashes into the Museum of Swordfish.
