Azhar Ali became the talk of the cricketing world - after being run out while chatting to his batting partner!
In the 53rd over being bowled by Peter Siddle, Pakistan's Ali appeared to strike the ball strategically in the gap between the slips in place. The left-arm seamer quickly threw the ball towards wicket keeper Tim Paine, who took down the stumps to dismiss Azhar Ali.
A rather amusing situation happened during the match when Azhar Ali played the shot through slips and was sure that it will go for four and started a mid-wicket chat with Asad Shafiq.
Ali appeared paralysed on the pitch as he was forced to come to terms with what happened.
Waugh and Brett Lee were quick to question whether the dismissal went against the spirit of the game but argued it was simply a batsman error.

"It's just a mistake from the batsman".
"If you're that stupid then you deserve to get run out", Waugh quipped.
Former Australia captain-turned-broadcaster Allan Border pulled no punches as Azhar trudged ruefully off for 64, describing it as "just total stupidity".
The first Test ended in a draw in Dubai last week.
No team has ever chased more than 418-7 to win a Test, made by the West Indies against Australia at Antigua in 2003.
Pakistan, who were denied victory in the opening match after Usman Khawaja scored 141 in the final innings, pushed their lead over 200 in the final session of day two.
