The usually cheerful and fun loving Abhishek Bachchan was seen carrying his father Amitabh Bachchan piggyback in their home production Paa. But in real life Abhishek himself likes to be carried around like that. One of his co-stars said that Abhishek looks very calm and collected but he is completely opposite. He is a real prankster and keeps the unit in splits with his antics. Perhaps his wife would be in a better position to tell that.
