The poll describes everything. I think it was To Love a Patty, with Fungus and Battle of BB next in line.
So go ahead and vote and tell your thoughts and reasons about these bad episodes of the dreaded season 5. I know a lot of people hate 'em.
Out of these five choices I'd say Atlantis and Waiting were the least terrible. The other three were just too nasty. I personally don't see how anyone can bear to watch them.
I'm so glad season five is over. Even though some episodes aren't too good in season six, it still is doing better than season 5 I'd say.
