I often crack my knuckles and neck to the point at which they become sore, then carry on... I bite my top lip so much that it now has a bit of hard skin in the middle that I bite off. Drumming on desks is another one.... Spinning pens/pencils around my thumb or flicking them into the air...
And for an OCD habit I have to sort things of different sizes into size order; coins, book, etc.
