A little more drama than comedy this week, but that's absolutely fine. Pontyberry is in party mood, with Luke celebrating his 25th and undertakers Bobby and Daddy trying to rehearse their duet. Luke's estranged dad is back, Jas is out to catch her man, and Stella joins Sean at the boxing club and spars with Joe Calzaghe. Yes, really.

Writers Ruth Jone and Rob Gittins juggle a lot of balls but still have time for joyous incidental characters and magnificent throwaway lines. That's just showing off.

It's Luke's birthday and Stella pulls out all the stops to make it a day to remember, but little does she know his real dad, Rob, is in town to join the party. "I'm your dad, Luke," says prodigal dad to disbelieving offspring in a nice nod to Star Wars. Meanwhile, Big Alan is getting a taste of his own medicine thanks to the relentless attentions of Nancy the amorous Brummie, and Stella takes up boxing, thus enabling her interaction with tonight's celeb cameo, Joe Calzaghe. Knockout.
