I saw Rublev live at the US Open this year vs Draper, with decent enough seats that before the match I told my wife, 'get ready to hear Bweeh! a lot for the next few hours.' Then, to my shock, he rarely used it. Toward the end of the match, I actually started yelling 'BWEEEH!' after every point he won, just to keep the spirit alive. Got a lot of funny looks, and the wife was pretty embarrassed, but I'm like 30% certain someone from Rublev's player's box looked over at me one time like, 'is there really some dude yelling bweeh?,' which made it totally worth it!
