During the Maps And Minions segment of Strong Badia The Free, two characters on the same space normally fight, but there are two exceptions- one is, if you have The Cheat and Strong Mad on the same space, they will refuse to fight and instead share a hug.
Strong Bad vs. Little Girl! Strong Bad can actually talk to a small child and not say anything offensive. Especially heartwarming is the ending, where they go see the sun.
At the end of Sbemail 200, The Paper (which had "died" several Sbemails prior) makes a brief cameo. Strong Bad was very happy to see it again.
