The southern gentlemen of Kings of Leon weren't so courteous on Friday's (Nov. 12) episode of "Late Night with Jimmy Fallon."

During a sketch with Fallon, the Followill family gave a not-so-warm welcome to Jimmy at a bed and breakfast they run, called "Slappington Manor."
Dressed in 1980s yuppie attire and ridiculous wigs, KOL gave the host the answer to "What do the five fingers say to the face?" Things started to get out of hand (pun intended).
Soon frontman Caleb Followil and Jimmy got into an all-out brawl (or at least as bad as a slap fight can get), but ended up calling a truce. In fact, Caleb says they're "besties." Aww, we've got the warm and fuzzies.
Besides goofing off a bit, Kings of Leon played its latest single, "Mary," a song about marriage that will soon become a reality for the recently-engaged Caleb. Sorry, ladies.
