I’m all about these food infographics. Found here. I also love all those little tricks unique to each fruit for finding the best, most delicious one. Examples:

Watermelon - place ear near melon, knock and listen for the most hollow sound.

Pineapple - gently tug at the spikey leaves, if it comes loose without effort, that’s your winner.

Berries in a carton - give the carton a little shake, if the berries roll around freely you’re guaranteed a less smashed or spoiled bunch. 

Now that I think about it, for all I know these could be fruit legends from yonder but I swear that knocking method brought me an intensely sweet and flavourful watermelon last week.
