Rab ne bana di jodi?

SRK can surely act and it definitely was one his best performance so far and movie definitely worth a one time watch. Now people have been saying that it was a realistic movie. Reasons:

1. SRK had mustache
2. He was working in normal cleric job and was speaking in desi English "same to same" or "Thanks he ji"
3. His friend Bobby Khosla (brilliantly played by Vinay Pathak) was a normal barbar.
4. The hip version (Raj naam toh suna hi hoga) was also very realistic and for a relief of audiences wasn't typical larger-than-life SRK image.
   

To them I would like to point out an odd- Just Because of different hair style and mustache his own wife couldn't tell that it was same SRK?
