Here's a Warner Brothers cartoon directed by Chuck Jones that you probably haven't seen. It's called "Drafty, Isn't It?" and it was made in 1957 for the U.S. Military. The voices were done by Daws Butler, who actually gets a screen credit. Daws was in a lot of WB cartoons and sometimes had the largest roles but only Mel Blanc's name got into the credits back then.
The lead character is Ralph Phillips, a daydreamer kid who turned up in five (I think) of Jones's cartoons — this one, one other for the military (for which his voice was done by Mel), and three "regular" WB cartoons where he was younger and voiced by Dick Beals. He never caught on and you won't particularly like this film but you might to watch a little of it because (a) it's a Warner Brothers cartoon from back when they were doing great ones and (b) the way things are going in this country, they may be reinstating the draft soon.
