New York (CNN Business) The maker of Miller Lite and Coors Light doesn't see the funny side of Bud Light's corn syrup Super Bowl ads.

Anheuser-Busch BUD MillerCoors filed suit against, the brewer of Bud Light, over the commercials, which it says are "false and misleading." It wants them blocked and its rival to set the record straight.

Bud Light's ads during Super Bowl LIII touted the fact that the beer is sweetened with rice rather than corn syrup. And they took jabs at its competitors.

In the first ad, the Bud Light King, Bud Knight and others are trying to figure out what to do with a corn syrup barrel that was delivered to them by mistake. They set out to the Miller Lite castle to see if the barrel belongs there, but the castle had already received its delivery of corn syrup. Finally, they make it to the Coors Light castle whose occupants have been looking for their corn syrup barrel.

MillerCoors said in Thursday's lawsuit that Anheuser-Busch "plotted an extensive and pervasive advertising scheme designed to frighten consumers into switching away from Miller Lite and Coors Light to Bud Light." It accused Anheuser-Busch of using corn syrup as a fermentation aid in drinks such as Stella Artois Cidre and Bud Ice.
