Reminds me of this one (I memorized this about 40 years ago)
Ladies and Jellyspoons
I come before you
to stand behind you
and tell you something
I know nothing about.
Next Thursday,
the day after Friday,
there'll be a ladies meeting
for men only.
Wear your best clothes
if you haven't any,
and if you can come,
please stay home.
Admission is free,
you can pay at the door
We'll give you a seat
so you can sit on the floor.
