Pistachios when eaten in plenty are more addictive than heroine... or so I've heard.
Chestnuts... a little too seasonal for my taste. Reserved for Christmas hearths only.
Walnuts come with the aggravation of having to break open their Galaxy-class tritanium shells.
Peanuts ... only good at the ball park, the airplane, or spread on toast with bananas slices.
Beernuts... unless they're free, they lose all flavour.
Now almonds rule! Especially when coated with milk chocolate. Too bad for the arsenic in them...
