Haha, what an awesome thread. I do a lot of weird shit, but I am crazy
I like dancing stupidly to anything rhythmic, like a train going past or to the sound of someone brushing the teeth.
I make the sound of the phone ringing or the cuckoo clock along with them whenever they go off.
I make up nicknames for all my friends - I still laugh at my friends 'food' names (so there was MIKElets, JIM sims, etc)
I'm always singing at the top of my voice around the house.
I like putting magazines in peoples' pillowcases so when they go to bed it's hard.
I hit my computer when it doesn't work, then apologise to it because I feel bad I hurt it!
I also talk to myself, but it's more saying my thoughts out loud than actually having a conversation
