Complete works of beef jokes

I have a funny joke-a cow was grazing on the roadside, and suddenly a bull ran over and shouted, Run, the expert came. As soon as the cows heard the noise, they began to run together. Running and running, the cow asked, what are you afraid of when the experts come? The bull said, you don't even know this. Experts like to brag. Hearing this, the cow ran faster. After a while, the cow said, no, why are you running? The bull said, you don't know, experts like to talk nonsense except bragging.
