Hypothetical situation

[NorthWestRugby]

World Cup. Only one Curry twin has been picked.
It's around 60 mins deep into the game and Curry twin #1 has put himself about the park all game covering for Billy Vunipola and Nathan Hughes who has come on at 6. Hes knackered but we have already used our forward subs. Curry twin #1 goes down after a 'head knock' and goes off for a HIA. After about 5 mins he returns looking fresh after passing the HIA. He comes back on and has a storming final 15 mins and England win the game.
Now, the opposing side are saying Curry twin #1 has been replaced with Curry twin #2 in an act of deception. How would they be able to prove otherwise or the opposition prove this has happened?

First off, love the phrasing of the question! Not "Could we do this?" but "How could somebody prove it if hypothetically we were to do this?"

I'm not sure they could. There are subtle differences between the two, I believe, but nothing you could show definitively on a television screen.

Eddie would have to have Dean Richards onboard to make it happen.

Let’s hope Curry no2 doesn’t wink.

I’ve heard murmurs that there’s actually four of them anyway.
