@Wimbledon Hello Wimbledon, after practicing today I noticed that my order of S+C had not been delivered. #getitsorted

@PseudoFed Good afternoon Roger, how is the tennis for you? It's a shame you couldn't stay for the S+C gala my mother hosted. #sad
Not Andy Murray @PseudoMuzz 3m
After my practice session, I took to Wikipedia to check my Wimbledon draw. #happydayshttps://twitter.com/PseudoMuzz
That didn't even bring a smile to my face, and nor did looking at the other tweets. PseudoRafa isn't any better either.
I seem to recall that somebody started a Pseudo Murray account once before (or maybe this is a continuation of it?) which was also a big fail to me.
The thing is that PF really is in a class of his own when it comes to clever parody, but then his subject presents such a wonderful target because of all his overt arrogance and ostentation. What can anyone possibly find in Andy, Rafa or Nole that comes anywhere close to Fed's foibles?
