Why the bike riders?

think Yiddish,
roll British

A story told amongst many post-WWI Talmud students:

In 1936 an elderly Jew was walking down a lonely street in Berlin. Suddenly he was accosted by three burly Nazi ruffians, who taunted him. One demanded angrily: "Isn't it true, old man, that the Jews are the cause of all the problems we now have in Germany?" The old man, no fool, replied, "Actually, it's the Jews and the bike riders."


The irate hooligan looked puzzled and asked "Why the bike riders?" The old man replied:

"Why the Jews?"
