if you have see enough abbott and costello movie and then you should know that the actual plot be unimportant while the whole movie be really just an excuse for bud and lou to get into embarrass situation and be silly . you would better believe that they do that in buck private . they play a pair of street vendor who inadvertently end up in the army . to make matter bad and their drill sergeant be the cop who go after them . once on the military base and abbott try to be serious and while costello somehow manages to do everything wrong and often incur their drill sergeant wrath . aside from abbott irritation and costello gaff and there some extra entertainment by the andrew sister and a they sing boogie woogie boy in company b and among other song . but like i say and the whole movie be really all about costello make a mess of everything . just how many movie can there be about some goof ball join the army and raise cain .
