I did laugh at this Olympic commentator last night

[thetemptationofchocolate]

Most of the ,misused words in the Olympic commentating team make me cringe, when they use the wrong word and you know that they really have no idea what it means.
I was watching last night when the commentator said,
"You don't have to be a rocket surgeon to do the maths on this". It was quite funny at the time but I do wonder if they realise how stupid they sound.

I apologise for the random comma in my post, I would have removed it from the post but I thought it was a bit of dirt on my screen.
