Mazel tov!
This dude, sitting at a bar mitzvah and holding a Torah, looks an awful lot like Los Angeles Lakers superstar Steve Nash, doesn't he?
(That's the Torah that Nash is holding, wrapped in a cover.)
Reddit says he is Steve Nash, and, I mean, Reddit's not exactly infallible, BUT: if you search "Steve Nash bar mitzvah" on Twitter — and I do this on a pretty regular basis, because obviously — there's some supporting evidence.
