Well, that’s one type of brotherly love.

On Friday, twin brothers (and No. 1-seeded doubles partners at Wimbledon) Mike and Bob Bryan were in the middle of a second-round match when Bob hit his brother with his own serve.

However, it looked as though there were no hard feelings; both brothers posted the moment on Twitter after they beat fellow Americans Steve Johnson and Sam Querrey.

Next, the duo will face unseeded Mate Pavic and Michael Venus in a third-round match.
