To soak or not to soak?

I have been planting peas for years. Some years I soak them first, some years I don't.

The only reason I ever soaked them in the first place is because my dad always did before he planted peas. I have never really noticed much of a difference in the outcome. I have read a lot of things about why to soak them, or why not to soak them. I have never been able to reach a strong conclusion on way or another.

So the question is, do you soak your peas before you plant? And if so, does it make a difference for you? Do you soak anything else? Beans? Your feet after a long day?
