Full Frontal Nerdity is a weekly webcomic by Aaron Williams (also the creator of Nodwick and PS238). It focuses on the roleplaying sessions of four tabletop gaming friends, all of them typical nerds in bad need of a life. The characters are:
Frank, the Game Master. Overweight and socially awkward.
Frank: "Due to rampant thefts, field destruction, zombie cattle, poisoned wells, attempted murder, and a relatively mundane aphid problem, your town can expect to suffer fifty percent population loss."
Basement Dweller: According to Nelson, everyone but him (although Shawn hadn't joined by then).
Batman Gambit: Frank runs a campaign featuring multiple factions interlocked in a power struggle for the throne, each of whom having their own plot hooks. Nelson and Lewis decide to accept as many plot hooks as they possibly can to maximize their XP and loot, thus ending up playing multiple factions against each other. They end up having to do a lot of political maneuvering, actual role-playing, and careful reading of the campaign notes to accomplish this without being detected and cut off from doing more adventuring... Which turns out to have been Frank's plan all along.
Frank: Okay, having gotten hopelessly lost, you're forced to spend the night in the forest. When your characters awaken, they discover that they'd been ravaged by dire mosquitoes to the tune of 3D6 worth of blood loss. As the vultures circle and the sun climbs, you begin to suffer heat exhaustion... Due to multiple insect bites and the fact that you had to sleep on the rocky ground, all your feat and skill rolls will be at minus five for the next day and a half.
Lewis: I vote that our D&D game gets a week off after your parents make you go camping.
Munchkin: Nelson. The Crowning Moment of Munchkinry was when he managed to finagle his way into ruling a fair chunk of the world and even appointed his character a god, complete with prestige class and Alignment Violation Coupons.
Shawn may be one as well. When the other players question how they can be certain his die rolls will be fair (they rely on him reporting the results, since he plays by webcam) he offers them each a +5 vorpal swordthat he randomly rolled as a show of faith.
Really, all three players are Munchkins. Nelson is just the best one at it.
What Did I Do Last Night?: The main characters went to a New Years Eve party at the "Goblin Hole" and look through their pockets to figure out what they did while under the influence of "Klingon War Nog". Frank finds a character sheet for the elf ranger from the D&D movie, Lewis finds a receipt for the Everquest sourcebooks, and Nelson (who hates anime) found Yu-Gi-Oh! cards.
When Frank's nephew entered a pine-box derby, Frank and Nelson drilled a hole "whose geometry looks straight out of the Necronomicon with a drill bit that may have gone through someone's skull" in the car. They blanked out at the pine-box derby; when they came to, they'd been dumped in a basement to scream themselves unconscious after tearing a hole in reality.
