A cowboy's tombstone

Rico says his friend Tex sends this:

Here are the Five Rules for Men to Follow for a Happy Life that Russell J. Larsen had inscribed on his headstone in Logan, Utah. He died, not knowing that he would win the Coolest Headstone contest:
  
1. It's important to have a woman who helps at home, cooks from time to time, cleans up, and has a job.
2. It's important to have a woman who can make you laugh.
3. It's important to have a woman who you can trust, and doesn't lie to you.
4. It's important to have a woman who is good in bed, and likes to be with you.
5. It's very important that these four women do not know each other, or you could end up dead like me.
