I can do a bunch of the things on this list:
raising/lowering either eyebrow; gleeking; tongue to my elbow or my chin; all the tongue-tricks; clockwise/counter-clockwise rotation; sneezing with eyes open; plus a few others: reach around my head with my arm and touch the same ear; touch my pupils with my finger and fold my eyelids without blinking; actually the eyebrow-raising and the gleeking often happens by itself, which can be socially awkward -- if you don't already know how to do them, I'd advise against teaching yourself.
