I think it takes a certain set of circumstances
Robust man, plus small elfin girls or children running at high speed, plus you need to hit them full on or you'll just trip around them and probably take a layer of skin off. It's rare to get a full rebound without the fat man also recoiling slightly.

She knows her stuff!

It's true
There are whole physics seminars devoted to women and children bouncing off fat men. Something to do with Einstein's theory of fatman/small girl relativity

I do know a perfectly robust Fat Man on whom we can test this
And I'm sure he'd appreciate a flotilla of elfin girls running at him.

(I'm probably too big to run at him and successfully bounce off)

Yeah it's like positive and negative sides of batteries
Elfin Girl + Elfin Girl = minor damage
Fat Man + Fat Man = massive damage
Elfin Girl + Fat Man = the bounce off.

Although I don't know what would happen if the fat man was running and the elfin girl was standing still. Probably some kind of steamroller effect. Further testing required.

I don't know if I'm a sufficiently fat man for testing purposes
but I'd be happy to 'steamroller' any elfin girls you might have to hand

for greatest effect
have them both running, ideally indirectly crossing paths.

doesn't matter who - crashing while running into someone who is also running will cause instant change of direction (and most likely a faceplant or two)

You sat at the back in the science lessons, didn't you?

Science evades me entirely
As does maths. I'm a creative type, we don't need maths! Although it did take me ages to figure out how to work out the circumference of a circle so I could make a skirt recently.

Poor attitude
I go to galleries, theatre and listen to music. You could at least watch Horizon once a week.

Bloody arty types.

I can't pretend to understand something
when I really don't.

I got As in all my science exams at school so my grasp must have been satisfactory. I just prefer language and the arts.

You've been to galleries and theatres, I've been to Eureka.

That's alright then

We recycled paper
and made it into a keyring.

I haven't been there since I was a kid, mostly because I'm worried it'll be one of those places that's awesome when you're a naive child and ultimately crappy when you're a cynical adult.
