Flo the Progressive Girl vs Geico Gecko Vs State Farm Agent (teleporting) Vs Alstate Guy (big intimidating black guy. You know who I'm talking about.) That would be hillarious. Flo would rap against the Gecko, and then one of them would accidentally say, "like a good neighbor, state farm is there. The state farm guy would show up, and finally, the allstate guy would show up like Neil DeGrasse Tyson.

Charlemane (or Charles Martel) vs Tokogowa

Ghost Hitler vs Ghost Vader

The Beatles vs One Direction

Sonny Liston vs Lebron James

George Lucas, Stan Lee, and Jim Henson vs Walt Disney

And anything starring Rhett and Link or Weird Al.
