Drawn Together Easter Egg - What Is That Plant Doing?

OK, I noticed this while watching an episode of "Drawn Together" for the second or third time. There is a scene in a newer episode (as in it aired sometimes Feb. 2006) where Xander has fallen in love with Captain Hero's gay alter-ego, Tim. Xander and Tim are in the lake by the house, swimming, and as the scene slowly back away from them, you can hear Xander say something like "It unbuttons in the front." But did you notice that as the scene goes away a tree comes into the picture, along with a phallus-shapped plant. If you look closer, the tree is shapped like someone's hind-end, and the phallus-shapped plant appears to be going into the tree . . .
