'See hypocrisy at his best': Will Smith is called out online as a resurfaced video shows him mocking a bald man

 The Fresh Prince quickly became the talking point of Sunday night's Oscars when he slapped Chris Rock on stage for making a joke about his wife's hair. 

Jada Pinkett Smith suffers from alopecia and Chris laughed at her expense, joking that she was ready for a role in GI Jane. 

Yet a video circulating on Twitter captures the American actor, 53, during an appearance on The Arsenio Hall Show in 1991, joking with bassist John Williams about his lack of hair.
