There are a lot of rumours that the 2 old guys playing some kind of chess in Psy's "Gangnam style" are Daesung and Seungri. The same thing happened in 2NE1's "Clap your hands", fans thought that their background dancers were Big Bang.

 

                      

 

  

 

I don't know... I've been speculating and watching HD clip on Gangnam style and the making of the MV but it's just not them.. Sure "Daesung's" nose is a bit crooky but how come his hair color is black? During their Alive time/album (what so ever) he had blonde hair and now he has grey hair, but in the MV the person who is claimed to be Daesung has black hair under the gray wig. And that doesn't look like Seungri's face either...

 

                                 

 

You can even watch the clips in 1800 HD but I don't think it's them...

Same thing with 2NE1's Clap your hands

 

      

 

That actually did look like GD :o I'm not 100% sure here either but the chance of the background dancers beeing Big Bang is somehow bigger than the old people in Psy's MV beeing Daesung and Seungri.
