Throughout the seasons, several people have questioned Liz's gender. She always replies that she is really a girl and "that doctor was a quack." She serves as best man at the weddings of both her former sex partner Grizz and her mentor Jack (accidentally marrying him in the process). When Gretchen Thomas tells Jack she thinks Liz looks like Jennifer Jason Leigh, Jack initially assumes she means Jason Lee. She also once demonstrates that she is easily able to grow a moustache (which she calls "Tom," in reference to the famous Mr. Selleck) in less than 48 hours.
