It looks like Ricky Gervais has acquired a bike this Christmas, but he has been having a few problems inflating the bike's tyres.
Earlier today the comedian – writer of hit comedy The Office – asked his 11.7 million Twitter followers "What ***ing pump fits this stupid **nt of a bike? Tried 2 different sorts already. Twat. #**ntBike."
We're not familiar with that brand of bike. Perhaps it's German?
Anyway, he was schooled in the intricacies of Presta/Schrader/Woods valves, and later said: "Thanks to Twitter I am now an expert in bicycle maintenance. Any questions? Just use the hashtag #**ntBike & someone will assist you."
Another tweet suggested why Gervais is getting into cycling: "Gonna get fit for January."
