True story:
Right before a friend of mine walked down the chuppa, he turned to a rebbi nearby and asked “please rebbi, do you have some last minute advise or words of wisdom before I get married?”
His rebbi, who has a great sense of humor, was put on the spot, neverthess answered,
“Marrige is like a bar of soap. It smells delicious ’til you take a bite out of it!”
And with that, he was whisked by his parents down to the chuppa. LOL!
