Mr & Mrs. Stein
Over the years I'm guessing he's learned how to:
1. manage his carpal tunnel syndrome
2. hold his breath for over a minute
3. work custom made bras in to the family budget
4. perform several forms of martial arts
5. conceal a smug grin
6. repair door frames and expensive vases
7. reinforce buttons and seams
8. perform chiropractic manipulation
