Mr. Lucky is elated to hear he's won, and when Guy says his prize consists of things covered with fur, he gets even more excited, thinking it's fur coats. But his excitement fades when Guy tells him what the prize really is: a mob of wonderful furry monsters (including Frazzle and Herry). He bolts to the studio to return them, but Guy refuses to take them back.
Incidentally, Mr. Lucky also appeared in a sketch at the movies with Ernie and Bert (which appeared as early as Episode 0666 like "Dialing...), where he gets exceedingly frustrated and annoyed at Ernie's constant emotional reactions during the movie. Here he has a higher, angrier voice, but is still performed by Jerry.
