Gardening's Best Part

Alright, listen up, chucklehead. You are obviously too dumb to get this joke, and based on the fact that you posted it, you are probably a total loser. The joke is a pun, using the word "hoes." "Hoes" in gardening are tools used for weeding. But "hoes" is also a slang term for loose women. So, the joke is playing on this double meaning to make it sound like the gardener is being promiscuous. It's pretty basic humor, but I guess that is what you need.
