Something I learned from 'CBS Sunday Morning'....
On this date in 1931, Alka-Seltzer was introduced to the world.
And Alka-Seltzer eventually introduced their enduring mascot Speedy to Toobworld.
A puppety figure like those to be found on 'Robot Chicken', Speedy belongs in the main Toobworld, unlike figures like 'Davy and Goliath'. That's because he interacts with real human beings, as seen below. (That's the legendary Buster Keaton as the mailman.)
Like the Pillsbury Doughboy, he must have crossed over from his original TV dimension.
Suddenly I'm hungry for marshmallow meatloaf....
