kline in his milk

there was a reliver named kline
who had a dysfunctional mind
the only things worse
than his brain-chemical curse
were the stats on his pitching line

ankiel, pulsipher, kline --- what is going on here? if the only qualifications you need to pitch for the cards are left-handedness and mental/emotional imbalance, then i could suit up for the damn team . . . .
