Now you know why one should never expect "bloopers" in animation ... or, for that matter, why animation was never made for "bloopers," inasmuch as the medium has no margin for error, to begin with.
(A few words of caution: It's been suggested that many of these "actual bloopers" may have been fabricated, in particular the legendary "Uncle Don" such, the incredulous delivery of "Sonny Tufts?!" and the one proclaiming "This is the Dominion Network of the Canadian Broadcorping Castration." Too, listeners should be aware of the content including sexual innuendo, double-entendre and spoonerisms.)
