Vaseline

The very young couple, having limited funds, returned to her
parents after the wedding for their honeymoon night.  The next 
morning the family gathered for breakfast and lunch without 
them. 

When it came time for the evening meal, the father asked
of his wife and their 8 year old son, "Have any of you see the 
newlyweds?" 

The mother replied she had not seen her daughter and new 
son-in-law.  The brides' younger brother replied that he had 
seen his new brother-in-law about 10 PM when he stuck his 
head out the door and ask him if he knew where there was 
any Vaseline. To which the young lad further added, that since 
he could not find any Vaseline that he gave him his model 
airplane glue.
