bark mitzvah
 n.— «In the long walk of history between man and dog, the bark mitzvah could be seen as an unexpected pit stop. Yet it was celebrated on Saturday night in the Bronx in a traditional way, with a party for family and friends of the 13-year-old that included a chopped-liver sculpture, choruses of “mazel tov!” (or, in this case, “muzzle tov!”), a cantor and gifts.» —“Today He Is a Dog; Actually, He Always Was” by Lily Koppel New York Times Dec. 20, 2004.
