The Old man stopping the Carousel

That was so funny in that dry upper class privately educated English style which i really rate. I never had him down for funny after only watching Psycho, Vertigo Rear Window but i have noticed a lot more now he slips in these little one liners that you barely catch

The old man offers to help and starts to crawl under the out of control Carousel, it looks really dangerous so one policeman looking concerned warns him to back off.
His partner then tells him 'do you wanna do it yourself?'
And the first Cop just say's ' no ah i guess he can make it'

It's blink and you miss it but they are all over the place. I love how he doesn't make a song and dance out of it in a lot of films they know when they are being funny or having banter but he is assured enough to just drop little sprinkles here and there
