THE Testicle Tour is making an unplanned stop - the studios of ITV's This Morning.
Darren Couchman and Richard Miller, of Clacton, are travelling to places with genitalia-related names, such as Cocks Clark in Essex and Prickwillow in Cambridge.
The idea is to increase awareness of testicular cancer, which 35-year-old Darren battled eight years ago, as well as to raise money for charity Everyman.
He will reach a much wider audience than first hoped, by telling his story to Philip Schofield on the daytime programme tomorrow.
"I'm really looking forward to it," said Darren who has three children and is married to Sarah.
"There's also a good chance that they'll want to inspect my testicle though - it'll be the most famous in Britain."
Darren said he and Richard had been well received by people on their travels so far, although they have been having some technological problems documenting their trip.
"We wanted to do a daily blog on our website, but our laptop keeps crashing," he said.
"Hopefully we'll get it sorted out soon."
Once the daily updates are up and running, you can read them at onelumportwo.org.uk From the site, you can also find out more about the Testicle Tour, and Darren's book, One Lump or Two, which explains his fight against testicular cancer.
