Behind jokes

1. Someone went to the laboratory, and the nurse pointed to a sign in front and said, "Non-undergraduate personnel are not allowed to enter." The man was furious and scolded, "I'm going to have a urine test and want a fucking undergraduate diploma."

2. Three people look better than who poops. The first person is S-shaped, and the other two people praise him. The second person is u-shaped, which is equally awesome. Third person solid equilateral triangle! The other two people asked us admiringly. Did you pull it out? "I'm finished!"

In the afternoon, I work alone in the office. A colleague in front ate too much at noon and farted wildly. It's so loud that this man can't help it. He cursed, "You can't fucking hold it, fuck." Finally, there was a moment of peace. When this man was refreshed, he suddenly saw the heir in front of him shaking wildly and asked, "What's the matter with you?" The man replied, "I'm afraid to disturb you."
