Tell Me A Fact

[Hopkirk]

Tell me something interesting, that I don't know.

I'll start.

On the London underground there are two separate stations, both called Edgware Road.

Male sperm wales sing a song to attract females.

During the mating season, evevntually every single male will learn and sing exactly the same song.

Also during the season, the song changes and adapts so that it finishes up being a competely different song from the one that started the season.

Every male learns the changes, and they are all singing the different song at the end, as well as all the permutations throughout the mating season.

Blimey!

Interesting fact: If you loop the loop in a Lancaster bomber, the chemical toilet goes straight though a bulkhead.
(Discovered by a pilot, at the RAF base my father was stationed at, on VE Day).

[Hopkirk]

I would have thought that a loop the loop in a Lancaster would risk the wings snapping off and meeting above the canopy.
Surely against RAF regulations.

[Buenchico]

The pilot did get court-martialled, Hopkirk, but because the act was done as a VE Day celebration, he got nothing more than a 'slap on the wrist' for his somewhat exuberant flying.

And that was the origin of the whale voice choir.

a domestic cat can run faster than usain bolt at his peak

[davebro]

a bloke woulda got a perfect score on Mastermind but his answer to "What is the smallest mammal" was "shrew" & the correct answer was "The European pygmy shrew".

"a domestic cat can run faster than usain bolt at his peak"

Commonly misheard, it's actually Usain Bolt and his peke.

Hot water freezes faster than cold water

Thanks for the link, Hoppy. The pilot who served with my father probably knew then that the manoeuvre had already been carried out (even if involuntarily) before, giving him confidence to give it a go himself.

[Hopkirk]

I thought Humpty Dumpty was a cannon.

[Buenchico]

Bob: YouTube is full of videos that aim to show that the Mpemba effect really exists. However I prefer to trust to science ;-)

Thanks Buenchico... read that but am still not sure either way

Pussy Cats don't ovulate until they copulate.
And... according to my Vet they breed like Rabbits.

• Cats are induced ovulators, meaning that they will not ovulate unless mating occurs. If the cat mates during estrus, a surge of luteinizing hormone will trigger the release of the eggs from the ovary. Once this occurs, estrus will typically cease within one to two days.

[Hopkirk]

That seems an eminently sensible way to organise things
