Also wore number 13. My lucky number. 
Wow. Always a shock when you had no idea they were ill like Chadwick Boseman. Sean was my favourite on Countdown, so gutted to hear this. RIP.
Absolute pisser 
Very funny bloke and good guy too by all accounts. RIP.

In his honour, carrot in a box…
Sad to hear about Sean Locks passing - echo what others have said, true comedy genius. He was very good at nailing how long to drag a joke out for and whether it needed to be a one line quip, or to be built up. A sad day 
Never even knew he was ill. Always threw a brilliant twist on all his humour. My fav:
My favourite comedian RIP Sean.
Very sad news about Sean Lock. Whichever show he was on, he was always the funniest person there.
Here’s a bit from Countdown.
RIP, genuinely funny guy.
thoughts and condolences with his family
Sean Lock was one of the best comedians of contemporary times. Genius timing, dead pan delivery.
Rest in Peace.
He did look sort of ill in that video.
Forever a legend for this… RIP
Just read Layne ‘Back to Back’ Flack died last month in his sleep. Only 52 No official cause has been given. He was one of the ‘young’ guns that made poker in the early '00’s exciting.
