Whenever someone says something that remotely relates to anything I've even thought I've heard on an episode of The Simpsons, I quietly play that exact scene in my head, word for word, and laugh out loud. Sometimes I actually speak the quote, hoping for someone to understand what I mean. When they ask WTF, I shake my head and they give me an odd look, but I honestly can't help it.

EDIT: I know this is horrible, but every time I see someone talking about how great their church/youth group is, and how they like living a "pure God-given lifestyle, unlike the non-believers" it makes me want to punch them in the face because it makes me feel like their 'superior' lifestyle somehow has more merit and meaning than my simple existential existance.

Shun the non-believers! Shun... Shuuuuuun!
