Bert's buddy on "Sesame Street"
I believe the answer is:
ernie
'bert's buddy on sesame street' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ernie that I've seen before include "Computer selecting Premium Bond winners" , "Machine that randomly selects Premium Bond winners" , "It picks Premium Bond winners" , "Eric's TV partner" , "Bondsman" .)
