Tweet Zoo is a 1957 Warner Bros. Merrie Melodies animated short directed by Friz Freleng.
[3] Audio from this cartoon was sampled by Paul McCartney on the song "Check My Machine", released in 1980 as the B-side to the single "Waterfalls".
The cartoon, set in a city zoo, begins with a tour guide showing various animal exhibits to visitors.
After the requisite "I tawt I taw a puddy tat" lines, Sylvester begins his latest pursuit.
In response, a cluster of birds land on his shoulders and head as he is walking away, muttering about his awful timing for going on a diet.
