Some problems, but not trash
Sorry man, it just doesn't seem real. Yea, yea, its a joke. right. But who asks anyone the same question the same darn way 5 times after receiving the same answer? It's not realistic. And because I'm focusing on that, I'm distracted and not really laughing.
Perhaps other tellings of the joke change the question a bit to give the discussion more of a build, like "Are you sure you don't have any bread?" or "I'm really hungry, and I need some bread." I'm no writer, but I think you see what I'm saying. There might be a progression or line of questioning, rather than a loop.
Somewhat related, I felt like the duck lacked vocal emotion. More variety in how he asks his questions (like in tone, cadence, power, or any other descriptor of speech) would add some dimension. The other lines were quite alright and enthusiastic.
Your drawing was well done. Consistently styled and effectively colored.
You don't really deserve the criticism. You're filling big shoes up on the front page.
