The fact that, even after seeing this about 4 times, I'm only now realizing hes crying over the plant. "The plant has friendly growths, however you, do not." He wants to be like the plant. As odd as that sounds.

I'm honestly guessing he forgot that Yvonne was his "child" for a moment.

I showed this episode to my father. He found it quite amusing and often quotes it.
In the middle of restaurants.
And most public places.
