Who has a good classic joke?

In a primary school, two students are quarreling. A said, "You ... if you scream again, I can call someone!" " ! 」

B said, "You ... you fight! I don't believe this ... "

Then A really went to make a phone call, and when he came back, he put a cruel sentence: "You will know how to die in 30 minutes! 」

At this time, B was extremely nervous, but he could do nothing. After 30 minutes, the school broadcast: "A classmate of B, you have a visitor, please go to the Academic Affairs Office. Although I am very scared, I think I should be fine in the academic affairs office. So he went to the academic affairs office, and a blond boy came over and said, "Are you someone? "? 」

B: "I'm ..." ....

"Sorry for waiting, this is 10 Hawaiian pizza with chicken, 5300 yuan."
