[after the Opening Credits' music concludes & the cartoon begins] Tweety is bathing, Sylvester looks at him (with binoculars, as Tweety sings in his birdhouse's bathtub & discovers the spying cat,) his remark is not the normal "Ooh, I tawt I taw a putty tat!" This time he says "Ooh, I tawt I taw a peeping tom cat."
The title is a play on the 1931 song "Sweet and Lovely."
Tweety has a personalized bath mat bearing his name.
Both the dog and bird houses are similar in design to the actual home shown, presumably where the owner lives.
Sylvester uses a modified pogo stick, which was a popular toy at the time.
