Why all the India references in my adsense banners Mr Google?

Can't explain why there are so many references to Delhi Appartment for Rent, Hindi Ringtones, etc., in the Google adsense boxes on my blog.

Come on Mr Google, talk about racial profiling. Just 'cos I'm a software engineer called Sagar, living in Santa Clara with links to Bradford does NOT automatically make me Indian ... though I could murder a Chicken Korma right now.
