4. The Squash
Prep: Admittedly, the squash was harder to skewer than the pear—however, the payoff still places the squash higher than sad ol' Mr. Pear. Or maybe Mrs. Pear? It's hard to find a pear's reproductive organs.
Effectiveness: The squash not only works like a charm, but it feels extremely natural to smoke out of—or, at least, as natural as you can get with your lips wrapped around a fruit. Yep, also a fruit!
