Eager to confer a measure of respect upon Dangerfield and upon Kew Gardens, Ballenas and some of the students at the school where he teaches helped get a memorial plaque made to honor Dangerfield, who died in 2004 at 82. Dangerfield lived in the neighborhood with his mother and sister in an apartment above what is now Austin’s Ale House, one of the best-known bars in Queens. The plaque, which bore the comic’s youthful image from his 1939 yearbook from Richmond Hill High School, lists three of his top film appearances: “Caddyshack,” “Easy Money” and “Back to School.” [...] listed are his 1981 Grammy-winning comedy record, “No Respect,” and his 1983 hip-hop single, “Rappin’ Rodney,” which, the plaque noted, reached No.
