Brooke to Hulk's GF: This Is What Daddy Likes

How the hell does Hulk Hogan tell his 30-something girlfriend Jennifer McDaniel (left) and his 20-year-old daughter Brooke (right) apart?!

Maybe Hulk can't either --- unless he rubbed lotion on Brooke's inner thighs and caught her panty dance on purpose!

Brooke and Jen compared notes while tanning together on Monday.
