6. In Metal Gear Solid 4's Final Boss Fight, Ocelot Will Kiss You If You Don't Fight Back
Kojima ProductionsThe superb Metal Gear Solid: Guns of the Patritots is a Hideo Kojima game, so of course, it's got to have a wildly eccentric sense of humour. During the epic final battle between Old Snake and Liquid Ocelot, players are able to allow Liquid to give them a friendly smooch on the cheek. How is it done? The battle goes through three "phases", each reflecting one of the first three games, and in the third, Snake Eater-focused phase, if the player doesn't fight back against Liquid, they will end up in a headlock, get a kiss, and receive the "You're Pretty Good!" trophy. If the stress of the awesome final fight is getting to you, it's a great way to relieve some tension and inject a little levity into the situation, and of course, it's completely in step with Kojima's idiosyncratic and very, very Japanese sense of humour.
