riddle time

 What is Santa's native language?

North Polish.   That's from my west coast brother.

What three numbers give the same answer when added or multiplied?

I'll let you figure that one out.

What special invention allows people to see through solid walls?

Can you tell that my exercise leader has been telling us riddles in class?  That's not a riddle, just a fact.  

Another riddle she asked was 'What is the only animal that can't jump (not counting me)?'

The answer to the riddle is 'an elephant' but that's not really true.  She did some research between classes and it turns out there are something like 26 animals who can't jump.  They include starfish, hippos, rhinos, slugs, snakes and giraffes.  Sorry, that's all I can remember.
