I thought the Davis Cup Radio commentary was quite funny and sometimes during an exciting point or an important moment I felt as if I was listening to a soccer match! During the Safin-Acasuso match, Acasuso has just broken for 4-2 in the 2nd set and the crowd is going crazy:
"Andreas Egli is asking for some peace and quiet so that the 2 players can get it on."
(I don't know if it's just me but I found that hilarious
I also liked that they were reading comments and questions from fans sent by email. Apparently, there was an email from Roger Federer too.
Another fan was asking the commentators if they took advantage of their stay in Moscow to learn a bit of Russian. After blurting a couple of words one of the commentators says "Njet"
and then the other one:
"Njet is what we've been getting a lot of."
