one of my first ever scripts was a Mount-Player-To-Hand :D It made he player like a real size minifig, very small; mounted him to the player; then disabled the mounters and mounteds ctrl+k (so the mounter couldn't kill himself so the mounted would be stuck, and the mounted couldn't leave and mess up mount variables...)
I first thought up the mount player to hand idea from a glitch. In v0002, I flew to someone. I landed on their head, but the second I did, the person was suddenly mounted to my hand. I was like "WTF" and started walking around while he spun, then he ctrl+k'ed :(
