Be careful what you say in the work canteen, because as one man discovered, it may come back to bite you in the bottom - literally (well almost).

While the rest of the world was throwing buckets of ice over their heads for the Ice Bucket Challenge, Grant Beagle made, what he calls a “foolhardy error”.

Mr Beagle, a non-food manager at Tesco on The Brook, Chatham, said: “I said that having a bucket of water tipped over your head was not a challenge and that maybe having it shot up your backside would be.

“The works canteen was not the place to have said that and it became my objective to undergo colonic irrigation for charity.”

The married father of four accepted the challenge and raised £200 for Diabetes UK, the store’s nominated charity in the process.

He said: “Every step of the procedure was explained fully and I felt I could ask any question, no matter how trivial.

“The sensation within my body was hardly noticeable. I thought I’d feel it whooshing around but actually it was more like butterflies.

“It is not humiliating. It is not embarrassing. It is not something to snigger about or cringe at. It doesn’t hurt. I didn’t have it under anesthetic. It is fulfilling and invigorating. It removes the toxins that drag you down in life.”

The procedure lasted about 40 minutes and Mr Beagle said he was kept at ease by talking to health consultant, Talita Wigg.

Mrs Wigg, 36, is the owner of Kent Detox based at The Court Yard, Holding Street, Rainham where Mr Beagle underwent the procedure.

She said: “It’s like an MOT for your body, making sure it’s working properly. It’s a deep clean and gets all the organs working together in harmony.

“Although Grant did it for charity, it is a medical procedure and helps people with digestive concerns. Especially at this time of year when people have overindulged over Christmas.”

Mr Beagle is now a convert and said: “Just a few days later I am feeling refreshed and de-stressed. My patience has been restored to its old level. I am happier and more easy-going. I’m looking forward to my next session.”
