During the war Groucho asks for trenches:
"We don't have time to dig them. We'll have to buy them made." (gives some money) "Here. Buy them this high" (points to waist) "and the soldiers won't have to wear any trousers. No, buy them this high" (points to neck) "and the soldiers won't have to wear uniforms. No, wait, buy them this high" (points to over his head) "and we won't need any soldiers."
During Chicolini's trial:
"Now, he might seem like an idiot and sound like an idiot, but don't let that fool you, he IS an idiot."
