A very young couple, having limited funds, returned to her parents after the
wedding for their honeymoon night. The next morning the family gathered for both
breakfast and lunch without the seeing the couple.
When it came time for the evening meal, the father asked of his wife and son,
"Have either of you see the newlyweds?"
The mother replied she had not seen her daughter and new son-in-law all
day.
The bride's older brother replied that he had seen his new brother-in-law
about 10 PM the previous evening, when he stuck his head out the door to ask if
he knew where there was any Vaseline.
As the father's face took on a knowing smile, his son further added, "I
couldn't find any Vaseline, so I gave him some model airplane glue."
