Anyone remember a comedy routine from the 1960s or so, an American comedian doing a Russian Red Riding Hood:

Wolf: Where are you goink?
RRR: To bring the grandmozzer some soup.
Wolf: Soup? Vy are you not at the Committee for the Stonink of Embassies?

(Or something of that sort.) My neighbour was telling me about this, and I'd love to hear the original. Who was the comedian and what was the skit called?
