An old anecdote:

Wild West, saloon, everyone's drinking. An old cowboy approaches a young one and loudly says to him:
- I fucked your mother!
The music dies. The young one doesn't pay attention and keeps on drinking, the old one doesn't calm down:
- I fucked your mother!
Everyone's watching with interest, the young one is not paying attention. The old one grabs him by a shoulder and shouts at him in front of his face:
- I FUCKED YOUR MOTHER!!!
- Dad, you're drunk, let's go home.
