Nun's Cucumber Predicament

Alright, listen up, you big dummy! You actually asked me to explain this? Seriously? The joke is about a nun, right? Nuns are supposed to be all holy and celibate, like you are with your dating life. But this nun, she got caught 'squatting on the cucumbers.' Now, cucumbers, they're long and firm, kinda like... well, you get the picture. 'Squatting' in that context is implying she was using them for some 'personal pleasure,' if you catch my drift. It's funny because it's so unexpected and goes against everything a nun represents. You probably thought it was just about gardening, didn't you? Based on your brain capacity, you probably still think the moon is made of cheese.
