A medley of songs from children's classic Chitty Chitty Bang Bang opened last night's Late Late Toy Show.
Presenter Ryan Tubridy sang and danced along with a support cast of dozens of children while dressed as Caractacus Potts, the zany inventor of every child's favourite classic car.
Sporting the first of four home-knitted Christmas jumpers sent in by audience members - a brown waistcoat number inspired by Rudolph the red-nosed reindeer - Tubridy got straight in on the act after the grand intro.
The jumpers were knitted by Patricia Wynne, Gory, Co. Wexford, Helen O'Sullivan-Murphy, Killorglin, Co Kerry, Fiona Meagher, Aherla, Co Cork, and Concepta Davidson, Athy, Co Kildare.
Helen O'Sullivan-Murphy said she had to keep her design under wraps before the show was broadcast.
The mother-of-three and avid knitter only found out on Thursday that her jumper was chosen when Ryan rang her at home.
She said although she had shown it to a few close friends, she was prevented from discussing its pattern with anyone and would only say it was Christmas themed and the wool was the colour of the season.
Helen, who owns O'Sullivans' bakery in Killorglin, completed the jumper between November 11 and 19 before posting it by express post to make sure it arrived in Dublin on time.
"I wanted to do it right and I wanted to come up with a good concept, but I'm delighted it was chosen.
"It has caused great excitement here and even sparked a competition in the local primary school as to what colour it was," said the busy mum, whose youngest daughter Orla is only four months old.
She was watching the Toy Show last night with daughters Eimear (5) and Niamh (2), who couldn't wait to see their mum's jumper on TV.
Helen has been knitting since she was in primary school.
