Big-Lipped Alligator Moment: In "Homestar Ruiner", Strong Bad can prank call his own answering machine. The call he leaves involves him making an impression of Homestar saying he's an "attwactive woman" wanting Strong Bad to come on over. Strong Bad then remarks that it was a little weird.
Not fond of Gel-Arshie, the creepy red gelatin mascot? Well, he appears in full creepy fashion in "8-Bit is Enough" and becomes one of Strong Bad's party members. And boy does he still have creepy moments.
Porting Disaster: The PSN editions of each episode are insanely glitchy, most likely in part due to the Dual Shock controller being a piss-poor substitute for a point-and-click interface.
Visual Effects of Awesome: In the cartoon, Homestar, Homsar and The Cheat are only ever seen from side angles, due to Limited Animation and their bizarre designs making it ambiguous as to what shape their faces are. They somehow managed to replicate this effect in 3D; look closely and you'll see that when the camera moves, their faces stay at the same angles, even though they're three-dimensional!
