from www.tmz.com – Octomom’s in luck — she’s been offered another get-rich-quick opportunity that doesn’t involve nudity … just some bizarre hair washing and a little tickle, tickle … for a fetish website.

Clips4Sale.com (the same site that offered LiLo $50,000 to pop some balloons) just sent Nadya Suleman a letter — obtained by TMZ — offering her $20,000 … and all she has to do is wash her hair on camera and put up with a little tickle torture.

The $20,000 can easily cover Octo’s $7,500 in back mortgage payments — and we’re told that might just buy her extra time to come up with the $450,000 she owes on top of that.

Coochi-coochi-coo.
