What's the most ridiculous argument you've had or overheard?

All I can here from outside is "HOW COULD YOU STEAL MY FUCKING PIZZA"

I hate people stealing my food so doesn't sound too ridiculous

A couple on the bus years ago , one dressed all in various shades of green, having a heated row . As they’re getting off the bus she shouts at him,

‘Oh yeah , but at least I don’t look like a fucking leprechaun ... who the fuck wears all green? You stupid twat.’

Whole bus was completely silent listening to them.

A while back we heard our next door neighbours son and his girlfriend arguing about pies

Walking behind a couple in Plymouth having a heated debate involving many names turned out they were arguing about Greek mythology

A couple arguing over a tin of sweetcorn in supermarket. He said they had loads of frozen in freezer. Her point was you always need a tin as you never know who is coming around.

They were full on arguing about this. I still cannot think of circumstance where an unexpected visit need a tin of sweetcorn.

Woman: WHAT COULD YOU POSSIBLY NOT UNDERSTAND!?

Man: OBVIOUSLY THE CORE CONCEPT!

Key Markets supermarket, Dorchester, July 1980. There was, shall we say, a misunderstanding, between the parents over whether or not powdered or tinned custard would be more suitable. It later developed into a full-on, classic Mum and Dad row. Over custard, for trumpet's sake. I christened the whole business 'Custard Commotion'. I was nine at the time. Is it any wonder M&D pissed me off so much, so often ? Twats.

The neighbour out the back of us absolutely screaming blue murder at her partner for eating all the crisps she'd bought for packed lunches. I'm talking screaming that hard her voice was breaking.

at the sweetcorn row

I don’t know what their arguments were about, but our old neighbours would have huge very loud shouting matches that would culminate in calling each other “thicko”!!
“You thicko!”
“Thicko? You’re the thicko!”
“Don’t call me a thicko!”
Etc, etc, etc...
We used to sit at our window listening and laughing. How can you have an arguement and not swear?!

Massive argument with DH (pre-marriage) about the interpretation of something in the New Testament. This came up in context of wider discussion about how we were both atheist, but brought up in quite/very religious families. So, we were arguing about something we both thought was not true anyway - but not true in different ways...
