Check Out My Daughter's
File this under things Hulk Hogan probably shouldn't have done -- publicly brag about his own daughter's sexy legs ... complete with the photographic evidence to back up his creepy opinion.
Hulk posted the photo of 24-year-old Brooke Hogan for his nearly 500,000 Twitter followers yesterday -- along with the caption, "Brooke's legs" -- which is kinda weird ... since ... you know ... HE'S HER DAD.
Still not as bad as that time he oiled her ass up though.
