Tucked, Taped and Gorgeous (S04E21)

When Greg (Matt Roth), a single father from Alan's support group who has been spending a lot of time with Alan, reveals that he is gay, Charlie suspects that Greg is attracted to Alan. Alan initially refuses to believe that his friendship with Greg is anything romantic, but he soon questions his own sexuality - as does Charlie. Meanwhile, Jake is too clueless to realize that Greg's young daughter is flirting with him. (Warner Bros. UK)
