Sam: About the Legend of the Milkman, from R. Ari Kahn:
R. Lichtenstein never volunteered as a milkman and R. Lichtenstein and R. Gustman were very acquainted long before this story supposedly happened. They lived near each other in Crown Heights, R. Lichtenstein was well known, R. Gustman was a close friend of R. Lichtenstein’s Rosh Yeshiva Rav Hutner and R. Gustman was at the bar mitzvah of the son of R. Lichtenstein.
