The Difference between "Happiness" and "Fucking" Comes Down to How You Use Your Thumbs and Forefingers: Good to Know

TV favourite Mr Tumble is greeting toddlers by saying “I’m f****** you” in sign language.

The CBeebies character says the gestures mean “I’m happy to see you”.

But angry parents have accused the BBC of jumbling up their signals.

Dad-of-one Jamie Miller, who works for the Royal National Institute for the Deaf, was stunned when he watched Something Special with daughter Katie, five.

Jamie, 32, of Northallerton, Yorks, said: “The signs for “happy” and “f******” are quite similar but it was still an awful error to make.

“Katie, who is learning sign language, asked what the gesture meant. I didn’t know what to tell her.”

Tell her the truth, that when she's older, she's going to discover that "fucking" and "happy" are pretty much the same things.
