But at least Mr. Rogers believed in Big Bird. XD
Yes, I've seen both Mr. Rogers' appearance on SS, and
's appearance on "Mister Roger's Neighborhood"; I know of what you speak. There's no way that Fred would've ever been dismissive of Big Bird; he's only 6!
Just to get back on topic, the B&E sketch featuring the repeating "H...H...H..." followed by Bert's stated enjoyment of "I..I..I..." scared me too.
