Keith, Rightfully Mocked

On each opponent's turn, he or she may make a good joke (as judged by you) at Keith, Rightfully Mocked's expense. If he or she does, he or she may place a +1/+1 counter on target creature he or she controls and you may place two +1/+1 counters on target creature you control.
"Good one. Ok, easy. Seriously, stop. Well, that was pretty funny."
