A bloke trying to do a very good thing for charity literally ran into a major problem after forgetting to factor in the additional surface area of his fancy dress costume.
Lukas Bates was taking part in the London Marathon over the weekend but, rather than just run it normally, he decided to up the fun factor.
Donning a Big Ben costume that towered one-and-a-half metres over his actual head height, Bates was doing quite well - until he ran into a wind tunnel at Canary Wharf.
There, time actually stood still as, with all that extra surface area, Bates legitimately couldn't continue to run into the wind.
Blessedly, someone caught the whole hilarious debacle on camera; check it below.
Bates was running on behalf of Alzheimers Research UK, and was attempting to "break the record for the fastest marathon dressed as a landmark", with the current record being held at three hours and 34 minutes.
While there's no word yet on whether or not Bates managed to crack the time, he did finish the marathon.
"Not all heroes wear capes," one Twitter user wrote before another replied: "Some wear big cardboard clocks."
