I came home one day about a year back, and I was about to make a Kale smoothie (red kale, green kale, oranges, blueberries water ice btw lol!) so she goes, "There's no kale left babes, you'll have to make another smoothie"
Im like "What the? There was at least 2 massive bunches of it in the fridge???"
Wife (innocently) "Sorry babes, but I made these and they're delicious" She goes over to the oven door and pulls out a massive tray of Blueberry muffins!!!!!!!!!!!
Me: "WOW thanks sweetheart you know they're my favourite right!"
"What did you do to the kale though babes???"
Wife: "Oh I gave it to johnny falcon, he said he was gonna make some 'kale chips' oh brother!"
Me: "Hahaha yes what a homosexual!"
jk - love kale chips, make em with a dash of oil (not olive as low smoke point) and plenty of Maldon Sea Salt
