Mohit Sehgal who plays Samrat in Miley Jab Hum Tum had to eat green chillies in order to lend legitimacy to a scene.
In the sequence Samrat and Gunjan (Sanaya Irani) enter a contest which required couples to eat green chillies. According to the rule, if one contestant backed out his /her partner would have to eat double their quota.
The scene required Gunjan to back out, so Samrat ended up eating 10 chillies instead of 5, but in reality he ended up eating 20 chillies due to retakes. The best part was that he did this without complaining.
