Poker Night At the Inventory/Fridge

Fridge Brilliance

 * It seems odd that Strong Bad bets the shades of Homestar's Dangeresque counterpart rather than his, until you remember his huge record for stealing things. Not to mention why would be bet his prized sunglasses?
 * You can win the Pac Man watch off of Tycho. It's no wonder we haven't seen it in the comic for awhile.
 * The watch normally finds its new owner through the murder of the previous owner. The Team Fortress 2 characters respawn whenever they are killed, with their current loadout. That's why the Spy still has it.
 * Max seems to be extremely lucky when it comes to getting that one card you need on the last river card. More so than the other 3 characters. Then you remember his latent psychic powers.
 * If you leave mid-tournament, and restart the tournament from where you left off, the eliminated players won't be performing their respective Funny Background Events - they'll have left. It makes sense that they didn't want to wait for you to return.
 * Max's collateral is the Lugermorph and the License to Maim, but the License to Maim has a 1 on it, meaning it's actually Sam's. At least that explains why he doesn't seem to mind losing it.
 * The Heavy apparantly has a fear of ghosts. This makes sense given that in his own game, there was a Halloween event featuring a ghost whose purpose was to immobilize players with fear. That, and the following year's Halloween event centered around a headless ax-wielding revenant.
 * Why does Strong Bad hate Tycho? Because he hates webcomics! There's even a specific Penny Arcade spoof in there to drive the point home!
 * Heavy thinks Huey Lewis is new, while Tycho is a little baffled at this notion. Heavy's been updated to modern times, but Russia (or at least, the area of Russia he lives in) is itself a few decades behind the times (which really happens in some out-of-the-way places).

Fridge Logic
"Heavy: Why does everyone think I love this Tetris? It is just stacking!"
 * An in-game example - Tycho assumes that Heavy likes Tetris because he's Russian. He doesn't.

Fridge Horror

 * The Heavy mentions at one point that he would like to make a hat out of Max. This could mean the Max's Severed Head hat from Team Fortress 2 is Exactly What It Says on the Tin.
