Put Their Heads Together

So, The Hero is fighting two mooks at once. How can he easily incapacitate both of them? Use Your Head! Or rather, he uses their heads- smacking them together and knocking both of them out.

Often has comedic overtones, despite being potentially fatal if done hard enough in Real Life. Sometimes used in place of a Dope Slap, although this variant generally does not knock the victims out. The comic variety is usually accompanied by a Stock Sound Effect.

 * It pops up in the first Artemis Fowl book, when Butler picks a fight with a bunch of dockworkers to provide a distraction for Artemis.
