Sister vs Wife or Girlfriend Fights

[Andy67]

Who would you bet on to win a fight between someone's sister and their wife or girlfriend, assuming both are evenly matched in height and weight? Also consider whether the guy in question has a good or bad relationship with his sister. So given they both hate each other, who do you think would be more motivated and who do you pick to win?

I remember I had a GF in school who my sister hated, I think she only hated her after I started going out with her though lol. They were fairly evenly matched, my sister was a bit taller but my gf was a bit bigger but I think they would have weighed about the same. They argued a couple times and I don't think my gf was ever intimidated by my sister. They never did fight but I think my gf would have won if they did.

Tre, did you ever ask either girl if they thought they could win a fight between them?

I didn't ask them, but I'm sure both would have said that they would win
