While reading some stuff about the characters I found this:

When Jane walks into The Dot to break up with Spinner, she chickens out at the last minute and tells him she's not ready to move in. It is also revealed that Jane is a transsexual. Raised as male until recently, Jane often has trouble learning certain social aspects of being a woman, such as makeup. Spinner does not mind that she has a penis, because most penises look like vaginas when compared to Spinner's penis.

Is this a true fact about jane? I mean the transsexual part, I don't remember seeing that on any episode...
