"Pork pies" is Cockney rhyming slang for "lies", as Melody said.  Like "Apples and pears" means "stairs".

My goodness that is one energetic monotreme!!!   Someone has been telling you porkies.

I seriouly hope that you are not Australian.   LOL

5455/(16*365.25)  km/day

$${\frac{{\mathtt{5\,455}}}{\left({\mathtt{16}}{\mathtt{\,\times\,}}{\mathtt{365.25}}\right)}} = {\frac{{\mathtt{5\,455}}}{{\mathtt{5\,844}}}} = {\mathtt{0.933\: \!436\: \!002\: \!737\: \!850\: \!8}}$$

Chris was laughing about my word "porkies"

Porkies is a shortened version of "pork pies"

Austalians used to be very into rhyming slang.  Pork pies rhymes with lies.

So if you are telling pork pies (or porkies)  then you are telling lies.

I am told that we adopted rhyming slang from the Brits.  (Engish)

-------------------

Also monotremes are mammals that lay eggs.

An echidna lays eggs but still feeds its baby with milk.

There are only 2 monotremes in the whole world.   The platypus and the echidna.  Both are native to Australia.

The male platypus has poisonous spurs on its back legs.  I just looked this up and I was very surprised to find that there are a lot of mammals that produce poison.  There is even a small primate in vietnam that produces poison.  How about that!
