Eli Manning's no J.Lo and Shakira ... 'cause the New York Giants legend's infamous "double bird" salute on "Monday Night Football" resulted in 3 pissed off viewers firing off complaints to the FCC.
Remember, EM goofed up on ESPN 2's "Manningcast" back in September while discussing how ruthless Philadelphia Eagles fans are ... claiming he would get flipped off by young fans, and giving visuals of how exactly that looked.
Manning later apologized ... but that didn't stop folks from writing in to the Federal Communications Commission about the salute, with one viewer calling it straight-up disgusting and calling for him to be punished.
