The film's promos, especially the songs have become quite a rage with youngsters all across the country and as if acting on cue, the makers decided to launch merchandise to cash in on the film's rising popularity.
Imran Khan sported a tee with DK Bose written all over it while Kunal was seen in a tee that had Switty -- another song from the film -- written on it.
Imran also revealed that it was mama Aamir Khan's brainchild to create T-shirts. The merchandise will be available in the market shortly.
Aamir had launched a similar promotional drive for his film Ghajini. Hope it works for Delhi Belly too.
