Mumbai: Actor Boman Irani is busy urging people to take a 'Smelfie Challenge' to rid their homes of odour, and now Bollywood choreographer-director Farah Khan has challenged her "Shirin Farhad Ki Toh Nikal Padi" co-star. Boman, who is the brand ambassador for Ambi Pur India, is inviting consumers to click ‘smelfies' with what they consider the most difficult household odour to get rid of, and send it to the #Smelfie contest platform during the contest. Farah took up the challenge, and said: "I have taken up the Smelfie challenge with what I think is the most difficult smell to get rid of - Fish! So, bring it on Boman, let's see if you win." "I was intrigued by this challenge by Boman! No one likes odours, especially me. But we all face it. So I am very eager to see if Ambi Pur is truly as effective in getting rid of home odours. I want to see if it can be my go-to for my lovely home. So, I have taken up the Smelfie challenge with what I think is the most difficult smell to get rid of - Fish! So, bring it on Boman, let's see if you win," Farah said in a statement. Under this contest, some winners will stand a chance to get invites to a house party hosted by Boman where he will demonstrate how Ambi Pur eliminates the household odours brought in by winners. The "Om Shanti Om" maker will now be seen joining Boman at his house party.
