A Freilekhn Gebortstog!
Two great Americans were sharing a birthday
Anyway, Dick -- as far as I know -- doesn't have a blog but you can click over to the inimitable Elisson and wish him A Freilekhn Gebortstog, which is supposedly happy birthday in Yiddish. I might note however, I've never heard anyone use that expression before and none of the other Yiddish speakers used it, so you might want to go with mazeltov instead. That kind of works for everything. But do drop by and leave your best wishes.
Happy Birthday El. Mazeltov from the northern south.
