My pet snakes will sometimes do the silliest of things when I take them out. The larger male will curl around my neck and flicker his tongue in and out of my ear, or slither down my top around and cling around... less than discreet places, as does the female snake. >.< He will also sometimes try and curl up inside my pockets, with just his head peeking out at the world, while she will attempt to slither into my clothes and out again. If you're ticklish like me, it can be very much so at times.
The smallest one, a mere baby, instead of taking his food, instead finds my fingers much more interesting and gently takes hold of the nearest finger (or thumb), and will suddenly clamp down and won't let go!
