Things I've learned from British folk ballads.Avoid situations where the obvious rhyme-word is "maidenhead."
Going to sea to avoid marrying your sweetie is an option, but if she hangs herself after your departure (and it's even money that she's going to) her Doleful Ghost will arrive on board your ship and the last three stanzas of your life will purely suck.
If you are a young lady and someone arrives to tell you that your boyfriend was slain on a foreign battlefield, take it with a grain of salt. Especially if you're carrying a broken token.
And many more. I'm sure it would be a lot funnier if I knew more of the references.

It really is good advice...nicely done
I need to start taking more life advice from folksongs.
