Saw new episodes last night and I'm pretty impressed.
Lost Matress: F-ing hilarious, now part of my top 5 favorites, 10/10
Krabs Vs. Plankton: This one wasn't nearly as good as 'Lost Matress', but it was still very funny (got better towards the end), I'll give it 9/10.
So far, for Season 4 (in my books, anyway), we've got two 10/10's (Fear Of A Krabby Patty/Lost Matress), a 9/10 (Krabs Vs. Plankton), and a 7/10 (Shell Of A Man), we just need a couple more 9/10 or preferably 10/10 episodes and I will officially conclude this season as one of the best ones. If they make less Patchy episodes this one may even pass Season 3 as the 2nd best (I don't think anything can replace what was the best saeson, Season 2), Season 1 is still definitly the worst.
