/> It isn't easy being a dancing-star. Even if you haven't danced for 20 years, filmmakers expect you to put on your dancing shoes and get jiggy.

Rishi Kapoor who in his heydays boogied the night away in Karz, Hum Kissise Kam Nahin and Zamane Ko Dikhana Hai, found himself once again being put into the dance mode by David Dhawan in Goa earlier this week while shooting for Chashme Buddoor.

With near-disastrous results. Rishi's knees have not reacted positively to the undue pressure. The actor rushed back to Mumbai to have it attended to by a medical team.

When contacted Rishi grumbled goodnaturedly, "Arrey yaar, this is not any age to dance and that too with Ali who's half my age and so skilled at dancing and singing on stage for hours. Lekin kya kare?

David wanted it. So...And now my knees are in bad shape. I am going through physio-therapy. Luckily there is a break in my shooting right now. So I am using for dubbing the time that my knees need to heal. "

Interestingly this was the second assault on David's knees within a fortnight. Earlier Rishi's knees took the brunt of another director Sajid Khan's enthusiastic desire to bring together two dancing stars Rishi and Mithun Chakraborty for Housefull 2 Says Rishi, "Yes, it was a double assault for my knees. Sajid made me and Mithun dance together, and we got carried away. I forgot I am no longer my son's age. Thoda zyada hoga. "

That's when Rishi's knee troubles began. Now with David Dhawan ‘s persistent request for some naach-naach-wink-wink activities to his dancing-actor from Deewana Mastana and Yeh Hai Jalwa Rishi's legs are in a state of heightend agitation.

Says the actor, "I got conned into dancing with Ali. That's not the only conning going on in Chashme Buddoor. I play the owner of a Portugese café frequented by Ali, Siddharth and Divyendu Sharma.

They never pay for any of their food and refreshments and humour me all the time. But on a more serious note, all the three young actors are a delight to work with. They are so good. The best thing about today's young actors is they don't copy anyone. "
