Black For The Groom

Little Moishie Rosenberg is at his cousin Hadassah’s wedding and asks his mom, "Mommy, why does the bride wear white on her wedding day?"
Moishie’s mom replies, "The bride is in white because she's happy and this is the happiest day of her life."
Moishie thinks about this, and then says, "Well then why is the groom wearing black?"
