When someone tries to get you to go somewhere, you mention you've got plans with Homestar and the boys.
When you write a Homestar Runner movie and try to get a deal with a Hollywood director.
When someone's house is on fire, you shout "Burninated!" (That's cruel, I know.)
When you reach for a bag of corn chips, a warrior pops out and slices you in half.
You make many Homestar Runner references in Mario-themed stories. (I am guity of this.)
While watching any movie with a swordfight, you yell "Sworded!" whenever anyone gets stabbed.
You say "I've gotta check-a my emails!" with your best StrongBad accent whenever you're on the computer.
You actually laught at the "Castlefunnies." (I don't know how that's possible!)
You commonly use insults from the mouth of StrongBad when dealing with people you don't like.
And the number one reason you know you've been going to Homestarrunner.com way too much is...
You write your own Homestar runner cartoons, SBemails, and even Teen Girl Squad toons. (I actually wrote a two part TGS story. It's totally sound recorded on my computer. I'll post the details of it later on.)
