Somebody tell a joke.

Xiao Li suddenly felt a pain in his stomach when he was shopping, so he walked into the hot pot restaurant on the corner 199 and wanted to borrow a toilet. But I couldn't find it on the first floor, so I ran to the second floor, which was still being renovated and empty, but I found a broken toilet door to be repaired. Please don't use it. I really can't help it. Anyway, I looked around. ! When I finished, I went downstairs and found no one there. Strangely, it's dinner time. Just now, I said downstairs at the wedding, why did you go to the building all at once? Even the waiter and receptionist were gone ... so I approached the bar and asked, "Is anyone there?" Why is there no one? At this moment, I saw a waiter coming out from under the bar and saying, *! ..... weren't you there when shit fell from the ceiling and hit the electric fan just now? You are very lucky.
