Guinness World Records (GWR) is celebrating its 70th anniversary by highlighting unclaimed titles you might fancy going for.
The bookkeeper of weird and wacky achievements - the first volume of which was published on 27 August 1955 - is inviting people to try their hand at such extraordinary feats as:
• The most whoopee cushions sat on in one minute;
• The fastest time to blow a stamp 10 metres;
• The furthest distance bottle flip;
• The most high-fives in 30 seconds;
• The fastest 400-metre sack race;
• And the fastest time to ascend the height of Everest by bicycle.
GWR's editor-in-chief Craig Glenday said the records are "there for the taking", and looks forward to celebrating "the next generation of record-breakers".
But it's not just quirky milestones that GWR concerns itself
