Officially amazing

In Competition No. 3019 you were invited to submit a limerick describing a feat worthy of inclusion in Guinness World Records.
 
This assignment is a nod to my nine-year-old son, who is a big fan of astonishing facts. Every year, when he gets his mitts on the latest Guinness World Records, he follows me around the house bombarding me with them. To the records I’ve recently expressed amazement at — most people in a camper van; most basketball slam dunks in a minute by a rabbit; tallest ever domestic cat — you added the feats below, winningly celebrated in limerick form.
 
Each one printed earns its author £9. Honourable mentions go to Clare Sandy, Jeffrey Aronson, Mike Morrison and Martin Parker. 
 

Though most Guinness records, it’s said,
Will not last in the days up ahead,
There’s one that is stable:
Cain’s brother, poor Abel,
Will always be ‘Man Longest Dead.’
Robert Schechter
 
A new Guinness record’s appeared,
And how Edward Lear would have cheered:
Four larks and a hen,
Two owls and a wren;
It’s official — most nests in a beard.
