there's an interview (in a French media) of Madeleine Barlöcher, who was responsible of junior players in Old Boys Tennis Club Basel, and especially Roger between 1989 and 1995, and there are funny stories :
- after the Orange Bowl he had tainted his hair in blond because of a bet but when Mrs Barlöcher saw him like that, he felt ashame ;
- one day he had made a smash and said "one day thanks to this smash I will win Wimbledon" and Mrs Barlöcher says that he did indeed win one of his Wimbledon titles with a similar smash ;
- he loved joking, for instance, during an interclub competition, he had hidden in a tree before it was his turn to play and everybody was afraid because they couldn't find him ;
- he loved swearing a lot in that time but he was not capricious in that time as he was later in Ecublens and when it became harder.
