Sam the Robot

Using Muppet Wiki . We solved a mystery. In one of Anne's old Sesame Street books we now read to Sam there is a reference to 'Sam the Robot.' While both of us grew up watching PBS we could not recall a cyborg muppet, but here he is. Apparently Sam the Robot was on the show from 1972-76. It is quite possible we missed out on him completely. Also found out that Kermit the Frog first appeared on Jim Henson's original show 'Sam and Friends.'
I guess he liked the name Sam.
