Smart / Good scenes which stand-out, from an otherwise mediocre or sub-par movie. Anything that you can think of?

Here are a few that I could think of -

1. Vengai - Ponnaambalam tells Raj Kiran that he is in Pondicherry (and not in Trichy). Raj Kiran knows he's lying & tells him to call back from a landline nearby. Ponnambalam is Busted.
2. Singham 2 (Good movie, but Sub-par when compared with its predecessor) - Vivek informs Suriya that Motta Rajendran has gone out to sea. Suriya tells him to send a dummy text message with delivery notification, and they'll know when he is near shore, and can nab him when he arrives.
3. Vedhalam - Ajith is speaking with Lakshmi Menon, who is stuck inside a car trunk and the car is in a traffic signal. He knows she's in one of the cars at the signal but not which one. He asks her to cut all the wires she could find. He sees the only car whose brake lights suddenly turns off (yet the car is still not moving) & identifies that as the car in which she is.
