Well, maybe you might want too…
This just happened tonight. I was on the road all day with my mom, driving my grandma home because she stayed the weekend. Now my grandma is really nice, but she can really wear you out! So tonight im a bit out of it from the long weekend. So I go into the kitchen and I see the flaucet part that sprays the water into the sink is gone. So, being the moron I am, i turn the water on to see what would happen without the attactment. BIG MISTAKE. Water flies 3 FEET ACROSS THE COUNTER TOPS, finally hitting the floor. It was pretty funny, but the counters and floor were covered with water, so I quicky cleaned it up before my mom would see. An angry tired worn out mom does not think a kitchen covered with water is funny 
Pretty funny stuff
Wait…did your grandma steal your faucet head??
Either way, too bad there’s no video of that, it must have been hilarious! Something similar happened to a classmate of mine in an organic chem lab. We were running a distillation, and one of the tubes connecting the water jacket to the sink popped off the apparatus…the tube went wild, spraying pretty much everyone in the room (and it was a BIG room!) The prof got soaked, but he’s a good humoured man! Lots of fun.
Then we had to clean up and finish the lab.
One day during my final (7th form in NZ, 17-18 yo) year of high school, I was sitting in the science lab listening to our Physics teacher, when I became aware of a muffled “clank” behind me. A quick investigation revealed one of my classmates doing something furtive with an adjustable spanner. He was trying to loosen the nut on the end of one of the radiators (waterfilled circulation jobbies), hoping to spring a slow leak. What he hadn’t considered was a tight thread and about 8 meters of head in the system (two stories in the block, and lots of radiators above us. The nut broke free suddenly, and he didn’t have a nice quiet deniable leak, he had a stream of rusty water (at least it was cold, it could have really hot) soaking the lower half of everyone at his bench, no nut to insert, and a spanner in his hand - and no explaination for the situation.
There was no way of stopping the water by hand - eventually we isolated the radiator and got the recovered nut back in, but the room was awash, and Physics was over for the day. The Radiators needed refilling and bleeding - a real mess. How he didn’t get suspended for that I don’t know, but is was a lesson in pressure
