Tommy Lee and his sons did NOT have a good father's day!

I don't know what went down between you and YOUR dad yesterday, but there's no way it was worse than this:  TOMMY LEE posted an old picture of himself with his dad, but in the caption, he mostly just talked about how awful his own two sons are.



He admitted that he wasn't always the best dad, but he complained about how they're spoiled and don't know the value of things . . . and of course, how their mom PAMELA ANDERSON had something to do with it.



He added, quote, "I love my boys but they can be [A-holes] too . . . and that's the truth.  (Cue Honest Guy music)"



It didn't take long for Tommy's son BRANDON to reply.  He said, quote, "Remember what happened last time you said this [stuff]? . . . You gotta show up to be a Dad big guy . . . I'm twice the man you'll ever be . . . Just move on... WE ALL HAVE.  You've done enough already."



Then Brandon posted a video of his dad UNCONSCIOUS on the floor . . . from when Brandon KNOCKED HIM OUT back in March.  And he captioned it, quote, "Look a little sleepy there Tommy."
