Just read a similar funny thread elsewhere, made me belly laugh.
Here's mine....
Had an argument with my then newlywed husband, while making cheese on toast. It was over who was having the nobby (the crust piece of the loaf).
I wanted the nobby and so did he. Rather than agree to share it, like rational adults, we stood arguing until my PMT hormones kicked in, and I yelled. "FUCK IT! Neither of us are having the FUCKING NOBBY, the dog is having the FUCKING NOBBY!"
With that I grabbed it off the grill and flung it at the dog, she was over the moon at her prize. 😂
We ended up falling about laughing. Our first marital disagreement over the nobby!
