Louis was also an adherent of laxatives, specifically one called “Swiss Criss”. He used to send out Christmas cards with a pic of him on the toilet, holding a box with the caption “Leave it all behind you”. He also gave a box of Swiss Criss to the Queen of England during his tour there.
I have such a signed card from him.
Louis was so popular that crowds of people would be in his dressing room. To make them go away, he would walk around the room, naked.
