Tell me a little joke, within 20 words, the shorter the better, don't look at it, make one yourself? Use your imagination and laugh me to death. Come on, friend?

1 I couldn't find my mobile phone at my friend's house that day, so I borrowed my friend's girlfriend's mobile phone and dialed it to hear where it was. Enter my number, and when I press the dial key, my name saved by her will be displayed on the screen: SB3 (then I feel gratified, fortunately I am the third runner-up ...) 2. I dropped a key when I was looking for my pocket, but I couldn't find it at that time, so I'll look for it later! There was a couple on the roadside, and the man suddenly said excitedly, Whose is it? Whose is it? I thought it was the key. Say it quickly, mine, mine! It is mine. Later I found out that the woman was pregnant. . . . Pity my face. . . It hurt for a few days
