Our reading
An editorial interpretation.
A joke about coming out that treats the news like a gift to be scheduled. Asking Mom to keep it from Daddy until a holiday like Father's Day or Christmas morning turns a big disclosure into a surprise present, and the humor comes from that mock-festive timing.
