Now that T.I. is a happily married man Hewpz’s vagina is living to fight another day! Don’t you just love a good come back story?

Shaquille O’Neal got more than he bargained for when he sat down for breakfast at a Waffle House in Tennessee last week — because the dude was the target of a practical joke that was executed to perfection.

Sources at the Waffle House — yeah, we got those too — tell us Shaq arrived with Hoopz from the VH1 reality show “Flavor of Love” … and they both saddled up at the counter.

We’re told they each ordered scrambled eggs with cheese and a waffle — and Shaq had an orange juice … an OJ that would play a key role in the prank when Shaq got up to use the bathroom.

We’re told Hoopz pulled the ‘ol “Dump the salt in the OJ” routine — and when Shaq returned from the can, he took a big, fat sip of the tainted concoction. We’re told everybody laughed at the gag … including the big man.

But the best part of the meal — when it came time to pay the $20 bill … Shaq left a $30 tip. (TMZ)
