It seems that a young couple had just gotten married and spent their first wedding night with the young man's parents. In the morning, his mother got up and prepared a lovely breakfast including freshly cut flowers from her garden and gourmet food. She went to the bottom of the stairs and called everyone to come down to breakfast. Everyone came down, except the newlyweds.
After a long wait, the family ate without them. The mother said, I wonder why they never came down to eat?"
The groom's young brother said, "Mommy, I think..."
"Oh, shut up. I don't want to hear what you think!" said the mother, not wanting to hear any inappropriate comments from the eight-year-old.
At lunch time, the mother again prepared a wonderful spread and again called the young couple to eat. Five minutes went by and she called again. After another long wait, the family proceeded to eat. As she was cleaning the table, mother once again said, "I wonder why they never came down to eat?"
Once again, the younger brother started to speak, but mother immediately shut him up. At dinner the same thing happened. After the meal, mothers once again questioned why they had not come down to eat all day. The young lad once again said, "Mommy I think..."
"Well, what is it that you think?" asked the mother rather testily.
"I think that when my big brother came down to get the Vaseline last night, he got my model airplane glue instead!"
