My mom used to say that Greek Easter was later because then you get stuff cheaper.

Sedaris’s line plays on the calendar difference between Western (often Catholic/Protestant) Easter and Orthodox (Greek) Easter, which frequently falls later. The humor comes from recasting a complex religious and historical divergence as a thrifty, almost opportunistic consumer strategy—waiting until after mainstream Easter to buy discounted candy, decorations, or seasonal goods. It also evokes a family voice: a mother’s practical, deadpan “wisdom” that reduces tradition to everyday economics. In that way, the quote gently satirizes how cultural observances can be experienced less as theology and more as timing, habit, and household budgeting.
