I laugh at a lot of things. Don't ever watch Tim Hawkins with me, 'cause you won't be able to hear his jokes over my laughter. Especially if it's his parody of, "Hey There Delilah". Or, "The Dog's On Fire". Or, "A Whiff of Kansas". Or any Tim Hawkins video.
I also laugh at well-made memes. Not that I'm capable of making them, but I still know a good meme when I see it. Meme Man memes, especially, have always tickled my funny bone for some reason that I have yet to figure out. Memes and comments with mixed caps also set me rotflmho (rolling on the floor laughing my head off).
As for what makes me cry, I really only cry when I'm fairly badly injured. And then it's not so much from pain (though it certainly does still have a part to play) as it is from frustration. I'm not really sure how to explain it otherwise. It's almost like when I get hurt, there's this voice that says, "oH WeLl dONe, PipPIn (Pippin is a nickname of mine. Don't ask.), yOu'vE hUrT YouRsElf." And it's more the anger from "hearing" that than the pain from the injury that makes me cry.
As for crying from emotional turmoil, rather than injury, that hasn't happened for at least a year or two. I was pretty close to it when my family and I celebrated Easter by watching The Passion, but it didn't happen.
So that's my answer. Hope you enjoyed reading it.
