Impostor Jerry

As an additional cost to play Impostor Jerry, you
must make another player laugh. If they do not
laugh, Impostor Jerry comes into play tapped
and does not untap during your next untap step.
All other Jerry's get +1/+0 as long as Impostor
Jerry is untapped.
Note: Honor system in play for this card.
"Laugh" also encompasses mild guffaws,
snickers or nasal exhalations.
