The days of the week as pharmaceuticals.

The last movie Groucho Marx appeared in.  Go out with a bang.

Monday is an antibiotic.
Tuesday is a hormone replacement.
Wednesday is a non-steroidal anti-inflammatory, NSAID, as some people like to say.
Thursday is a an anticoagulant.
Friday is a mild sedative.
Saturday is a cathartic.
Sunday is a placebo.

'nuff said.
