Agnes had 13 children

Agnes married and had 13 children. 
When her husband died, she married again and had 7 more children. 
Again, her husband died. 
So Agnes remarried and this time had 5 more children. 
Alas, she finally died. 
Standing before her coffin, the preacher prayed for her. 
He thanked the Lord for this very loving woman and said..
" Lord, they're finally together."
 One mourner leaned over and quietly asked her friend...
 "Do you think he means her first, second or third husband?" 
The friend replied... 
"I think he means her legs."
