Ed Asner and Sally Struthers Groping and Spanking

Ed Asner not only copped a feel Sunday night ... he oil checked Sally Struthers.

The 86-year-old -- who filed for divorce last year -- presented an award to the "All in the Family" star and macked on her like a 20-something stud.

Truth be told, if Sally wasn't down with it, it would probably qualify as assault, but no harm, no foul.

You gotta watch the whole video. Sally ends splayed out on a chair.
