Wanted

"Your blog should have a Moustache-Monday!", he said.

I really like the idea, I do.
It would match perfectly with my
Wish-Wednesday, Foto-Friday
(re-named by him and written with double F from now on)
and List-Tuesday
(oh camoon, let me have one weird combo with no matching letters).

Just one question:
What happens on a Moustache Monday?
Ideas, anyone?
