Perfectionist Aamir Khan recently launched the second poster of his film 'PK'.  And we guess that the superstar was in a jovial mood during the event as he challenged his close friend Salman Khan to drop his pants.

Salman was seen promoting Aamir's last release 'Dhoom 3' by donning the hat Aamir had worn in the film. Hence, Aamir said that he would want to test Salman's friendship and see if he drops his pants in order to promote 'PK' too.

"During 'Dhoom 3' my cap got very famous and Salman was wearing the cap on 'Bigg Boss', so, now I want to test his friendship. So let's see can he do this - he removed his shirt, now can he remove his pants?" Aamir asked humorously.

While the first poster had Aamir posing 'almost' nude, the second one sees him fully clothed, sans any transistor but with a trumpet.
