I've seen pictures with Dhoni bowling you think he will be the next all rounder, yaara, if they need a part-time bowler / full-time batsmen, bring in Imran farhat (I don't know who to replace him with) who has performed well as a bowler in firstclass level.
Most probably they were just having fun, you know Younis Khan character, fun loving, people person.
Note: Who bowls wearing a hat seriously

Farhat is more than all-rounder than YK! =P
He bowled in the test match against India, he was not special!
