I had a totally dumb/awesome idea for a commercial parody for True Grit Toothpaste.  Basically, the toothpaste just turns you into Jeff Bridges from True Grit.  I think it might be actually filmed, but here are some potential slogans.

True Grit Toothpaste: Brings Out the Cowboy in You

True Grit Toothpaste: Smooth as a Cactus

True Grit Toothpaste: Now With 33% More Sand

True Grit Toothpaste: Now in Three Flavors: Sarsaparilla, Tobacco, and Horse

True Grit Toothpaste: Not For the Yellow (pronounced Yeller)

True Grit Toothpaste: Shine Up Dem Choppers

True Grit Toothpaste: Makes Your Mouth Prettier ‘n a Two-Bit Whore

True Grit Toothpaste: For the Truly Grizzled

True Grit Toothpaste: Hog-tie Your Plaque

True Grit Toothpaste: Banned East and West of the Mississipp (very important the final ‘i’ is left off)
