Just playing around blogger settings and noticed the transliteration feature and thought I will give it a shot.
Hindi - आती क्या खन्डाला? (Will you come to Khandala?)
Tamil - இது ஏப்படி இருக்கு? (How is this?)
Malayalam - എന്ടെ ഗുരുവൌരപ്പ! (My lord!)
That was easy!
Disclaimer - I think the above is mostly correct, though the scripts I studied are slightly different from what is generated on a computer screen.
