Clippety Clobbered

In the mid to late '60s, Warner Bros. animation was slowly but surely coming to a close. "Clippety Clobbered" is a prime example, as Wile E. Coyote receives in the mail a non-Acme product to help him catch Road Runner. Naturally, this one fails, as do his subsequent attempts. However, I notice something different about this cartoon. Whereas in most of the WEC-RR pairings, RR usually doesn't even seem to notice that WEC exists, here he does. In fact, RR plays some rather cruel tricks on WEC, and even runs away at the sight of WEC (does he finally realize the potential danger?).

So, it's an OK cartoon, but the formula was pretty much spent by this point, so nothing looks particularly new.
