BASH and YES or ECHO cannot send "!"

[Mike McCarty]

I have come across an interaction between bash and yes or echo.

$ echo "Hello there!"
bash: !": event not found
$ echo "Hello there\!"
Hello there\!

So there seems not to be a way to display that string.

Oh, wait, apostrophes work!

$ echo 'Hello there!'
Hello there!

Interesting...

I can explain it for you, but I can't understand it for you.
