I just wanted to do this since I got really tired of waiting so long for the Telltale staff to write it. So here are a couple of things I've found.
In SBCG4AP Episode 5: 8-Bit is Enough, did you try...
...listening to a "very special light switch rave"?
...looking at your messy pile after getting Homestar's cell phone?
...going outside before getting the Trogdor key from Strong Sad?
...saying both the angel and devil options when talking to Homestar about Lucky George?
...giving Homestar the key to the Trogdor machine?
...putting Lucky George into the Trogdor machine yourself?
...saying 1, 2, or 3 during Videlectrix's "voice mail"? Twice?
...calling Videlectrix a second time?
...getting thrown out of the house by the Redcoat ghosts before AND after getting the light-gun?
...looking at the CGNU pennants before putting in the logic board AND after ridding your house of ghosts?
...repeatedly talking to the Drive-Thru Whale before AND after putting in the logic board?
...repeatedly talking to Coach Z while the Pitfall scorpions are attacking him?
...repeatedly getting yourself killed by the scorpions?
...getting ye flask? At least four times?
...asking the innkeeper about ye flask after trying to get it?
...repeatedly going on fetch quests for the evil wizard Slushfuund until he starts repeating himself?
...saying all three of the devil options to Strong Sad? And all three of the angel options?
...using the medkit on Strong Sad?
...getting Strong Sad out of the way of Trogdor's lair BEFORE getting the Trog-Sword?
...lose so much health in the Trogdor 3D hallways that a health pickup comes up?
...use up so much ammo in the Trogdor 3D hallways that an ammo pickup comes up?
...get yourself killed by the KOT?
...get yourself killed by regular Trogdor?
...using Gel-Arshie and the light musket on regular Trogdor?
...using your light-gun on ULTIMATE TROGDOR?
...talk to Homestar twice before using Gel-Arshie on ULTIMATE TROGDOR, twice after, and one final time after defeating ULTIMATE TROGDOR?
...turning your hints up to high and not solve puzzles no matter how obvious?
Also, look for Dangerzone's extra entries later down that I was too lazy to write on here!
