There's one version that thought didn't do anything.
e.g. 'I didn't know you were going out this evening'
' Oh. I thought I told you.'
'Well, you know what thought did.'
My mother in law once said 'Thought thought he'd sh*t himself and when he looked he had' and I thought "What?!".
So my old boss once got cross with me for doing something wrong. In my defence I said "...but I thought..." and he interjected "You know what thought did?" to which I answered "thought he'd sh*t himself?". My boss retorted " NO ... F**K ALL". Lovely. Poetically nuanced humour wasn't what he was known for.
