BotB- Any scene with Strong Bad getting beating with Carol. Also, when Limozeen says "Don't make us come down there, punk!"
Strong Badia the Free- Bubs shouting "Quit while your ahead!", and Homestar talking about the seige, but then failing, and finally, the Of Town saying "Aw crap." at the end.
Homestar Ruiner- I'd have to replay it to say what.
Strongsadioware thinks you're incredibly awesome!
