In "The Satue" Episode did the actor, (Raymond Mochinski A.K.A. Ray Thomas) really steal the staue from Jerry's apartment, although the circumstantial evidence may seem overwhelming the episode never really says whether or not he actually stole the statue.
BTW here's some great lines from this episode:
Elaine: I couldn't do anything Lippman loves Rava, not to mention Ray, and he doesn't think your funny at all!
Elaine:It is a coincidence. Rava:Yes, thats all just a coincidence. Elaine:You have to admit it is a big coincidence. Rava:No there are no BIG coincidences and small coincidences, theres just coincidences. Elaine:No, no there are degrees of coincidences. Rava: (to others) Are there big coincidences and small coincidences or just coincidences?... Well , well. Man: Could you please put that cigarette out Rava:maybe i'll put it out on your face!!! Rava: Its just like Ray said, you and Jerry. You are jealous of our love you are trying to destroy us! Elaine: (smug) Shouldn't you be out on a ledge somewhere?
