Moliere 
Imaginary Invalid 
Le Malade Imaginaire

The Imaginary Invalid is a three-part comedy about a miser who imagines illnesses for himself, and whose doctor milks his hypochondria for everything he can get. Their mutual greed and dishonesty lead to their downfall. It was the last play Moliere ever wrote, and he collapsed whilst playing the hypochondriac, shortly before he died. The play originally included dance sequences and musical interludes.
