"I Don't Know"

Intertwine your arms, right arm over, left arm under.
Play starts counter-clockwise.
Hit table with palm, and then it goes to the next person.
Hit table with fist, and skip one.
Hit table with palm twice, and change direction.
If anyone delays or screws up, they pull that hand out.

Variations invented at Herrang, '03:
1) Fist twice everyone pounds fist twice and then play continues on
   as normal.  (Not difficult, but damn funny).
2) Hitting table with back of hand means that next person has to
   hit table three times:  back, palm, back.
3) Back of hand twice is #2 but with reverse as well.
4) Hitting table with fist but with finger pointing in means
   everyone piles hands into center of table.  Last hand in
   is taken out.  (This one is likely to cause injuries ;)
