The ones I'm thinking of were almost like sirens, I dunno what to call them. They had a spinning thing inside a little tube that you blew into. I'm sure we got told many times; "Go play outside!"

Yes, I remember those well. I once actually heard one of those sirens, or something remarkably like it, used as part of an Arthur Fiedler / Boston Pops orchestra performance of "Teddybear's Picnic." :D

Heh! That song is so deep in the mind already! Hearing it with sirens musta bored a hole right through! You still hear it!

The siren was sounded immediately after the word "Surprise!," if you can imagine it fitting in there so very, very well... :D

Now we know how to trigger an episode for you!

"Surprise!!"

Hahahaha! LOL! :D

I'll try to remember for another day :)
