1.) Too many to name them all, but I'll give you a few.
-- ...Castle? ...Castle? ...Castle?
-- HE SHAT ON ME!

My best friend Krystiana and I were hanging around her house, and her older sister came into the living and said, "Hey guys, did you know that goldfish have a memory span of only 2 seconds?" And Krystiana, somehow totally misinterpreted what she said, and replied, "What do they do with the second one?" And we're just like, "uhh...wtf?!" And she said, "How can they have 2 memories? Do they use one for bad memories and one for the good memories? Is that even possible?!" And we were like, oh lord.... so we explained it to her. She finally got it, and we kept teasing her about it, and the conversation went on to what a goldfish thinks when he sees a castle in his fish bowl, thus "...Castle? ...Castle? ...Castle?" XD
-- HE SHAT ON ME!
During lunch, my friends and I always go and play on the high-jump mat. Well, the other day these guys came over and started jumping on it as well. I was talking to Kristin and eating a bag of candy when this fat dude "accidently" fell and sat on me. I started yelling "HE SAT ON ME! HE SAT ON ME!" really loud, and since I had a mouth full of candy it sounded like I said "HE SHAT ON ME! HE SHAT ON ME!" lol.

3.) Inside jokes just kinda... happen with us. O_o;
