Sue Perkins has joked some of "The Generation Game" contestants "needed counselling" after appearing on the reboot.
The 48-year-old comedienne and her comedy partner Mel Giedroyc are to host a new-look version of the classic hit game show on Sunday (01.04.18), and the pair couldn't stop laughing while presenting the new series.
Sue said: "We don't want to spoil the surprise, but we witnessed some of the most graphic teapot spouts ever made on television.
"So graphic, some of the contestants needed counselling afterwards. It took us about an hour to stop laughing."
The presenting pair feel "privileged" to be taking the reins of the programme - which sees four family pairs from various generations battle it out in a series of games, such as sausage making, plate spinning and Bollywood dancing - but they didn't take the responsibility "lightly".
Mel said: "It's a privilege. This is one of the most cherished entertainment shows of all time and we don't take that lightly."
Sue added: "We've stayed true to the spirit of the original - we meet great families and we try to give them the best night of their lives."
The pair - who will be joined by several stars including Richard Osman, Lorraine Kelly, Roisin Conaty and Melvin Odoom - have heaped praise on former "Generation Game" host Sir Bruce Forsyth, who passed away last year aged 89.
Sue said: "We grew up with Brucie, and they don't make them like that anymore.
"He was the only entertainer we can think of who not only had a catchphrase, but a personalised silhouette - that bent leg, fist to forehead stance."
Mel added: "As soon as you saw that, you knew you were in for a good night. He was a one off, a legend and an utter gentleman."
