Wikipedia informs me that while zucchinis are treated as vegetables, they are botanically a fruit, being the "swollen ovary of the female zucchini flower". I will never eat a zucchini again.

Theoretically, the strip title is supposed to be some kind of joke or pun - but now I have no recollection what it was supposed to be. I probably wrote it half-asleep.
