I've long wondered why Sylvester has to suffer so in the Looney Tunes/Merrie Melodies cartoons. Whatever the reason, he sure gets a whipping in Robert McKimson's "Lighthouse Mouse", as a sleep-deprived rodent and Hippety Hopper join forces to keep the light turned off. And then the lighthouse owner gets on Sylvester's case. Go figure! Yes, Sylvester always gets the short end of the stick, but these cartoons always consist of good taste. Whether up against Tweety, Speedy Gonzales or Hippety Hopper, Sylvester always provides his fair share of laughs. I hope that Warner Bros. starts releasing Hippety Hopper's cartoons on DVD sooner or later.
I guess that this cartoon also functions as a last look at lighthouses. With the sophisticated technology that ships now have, lighthouses have long since become obsolete.
