Ask for a comedy movie, the protagonist is a fool who goes to the city to earn money, looks like a big boss, and someone wants to stab him.

Dude, do you finally know what movie it is?

I'm also looking for a funny movie, similar to what you described. The story seems to have happened in a big hotel. I saw it when I was a child, but I can only remember some fragments.

1, the fool and his father went to town, the old man got stuck with too much luggage, and the fool pricked his father with a toothpick;

The killer got off the plane and made a phone call. As a result, he stepped on the air and fell down.

3, the fool ate the tribute pill, and as a result, he fell into the woman's underwear and put his hand in it to fish;

The killer plays a Japanese geisha, and the poison powder is hidden in the ring to prescribe medicine.
