Most networks (including CN and Boomerang) remove the entire final scene of this cartoon, which is the REAL ending. It goes as follows:
After seeing Bugs get all the cheers one more time after a juggling act, Daffy decides to try his ultimate act so he can finally impress the audience. Daffy appears in a devil outfit and starts drinking gasoline, uranium and gunpowder. He then lights a match and swallows it, exploding in front of the audience. The audience finally cheers Daffy, and Bugs, who is also applauding, and tells Daffy they loved it. Cut to Daffy in who's floating up to heaven, replying "I know, I know! But I can only do this once!" Fade out, that's all folks.
If you want to watch the complete cartoon, buy the Looney Tunes Golden Collection #2 DVD, the whole cartoon is there.
