'Meet the Parents' Star Teri Polo -- Meet Your Nipple-Free Tax Lien

Ben Stiller: I milked a cat once ...you can milk anything with nipples.
Robert DeNiro: I have nipples Greg could you milk me?

Probably not. You also can't milk the U.S. Government ... which just slapped "Meet the Parents" star Teri Polo with a chunky tax lien ... to the tune of $122,000.

Uncle Sam filed the lien earlier this year against the actress -- who played Ben Stiller's wife Pam Focker in all 257 "MTP" sequels.

According to docs, Teri still owes taxes from 2011: a cool $122,929.07

Teri apparently made a killing that year ... starring in a TV series called "Man Up", guest starring on "Law & Order" and "Castle" and filming a bunch of XMAS-themed TV movies.

Mother Focker.
