Jono was explaining to Shaz this new butter knife life hack he's recently found out about:
You simply insert the knife into the side of the bread to de-butter the knife and you've got a clean knife again!
That's Jono's life hack so Shaz doesn't have to put a butter knife in the dishwasher ever again.
But Shaz really can't wrap her head around it even after all that explanation from Jono. 😂
