What's the name of Degang Guo's crosstalk "Cow Dung Duo"?

When talking about traveling with his girlfriend and getting lost, Degang Guo woke up from his sleep. His girlfriend told him good news and bad news. The bad news is that after we get lost, we can only live by eating cow dung. The good news is, "There is plenty of cow dung! ! ! ! ! ! ! ! ! ! "

Actually, to be honest, it's a traditional joke (I can't tell whether it's domestic or foreign). Degang Guo, apply what you have learned.
