I had all four of them at once, I remember waking up in the surgery room and bumping the instrument table and going, Woopsy!, then continuing to follow the nurse who insisted on holding my arm, I'm not her type though.
I fell back asleep in the recovery room, woke up to find I hate 6 fingers on one hand, comes to be I had my hands behind one another, lol, you shoulda seen me shake my hands..
