question about episode The Gymnast

I have a question. At the end of the episode the gymnast says to Jerry basically in Romania comedians are the hot shots, but also says that even though Jerry tells jokes he is no comedian. What brings upon this little tirade? Is it because Jerry makes that remark about "Break a leg" before her friend goes to do the high wire act or is it something completely else?

If i recall correctly in that episode, Jerry (as well as most of the population) thinks that gymnasts would be great in bed, better than any average person. The joke is that in Romania she says that they are considered idols (we are led to believe that she is referring to them being great in bed as well). In the episode, jerry was not thrilled with his sexual experience with her saying that it was just like it was with a normal person. I am led to believe that she felt the same way. Thus telling jerry, "You tell jokes, but you are no comedian". I think that is what she is referring to. Anyone else? Brian
