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.

"Shorty had other two guards each by neck; he grinned as he cracked skulls together. They popped like eggs and he yelled at me: "Git!""
 * Caramon the Warrior is fond of doing this in the early Dragonlance books.
 * 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. He mentally comments on how cliche it is, not to mention being ridiculously inefficient from a martial-arts standpoint - but since the whole point of the fight is to be loud and spectacular, he uses it anyway.
 * A lethal version occurs in Robert Heinlein's The Moon Is a Harsh Mistress during a riot.


 * Happens a couple of times in Animorphs, often courtesy of Marco's gorilla morph.
