At Kottayam (Kumarakom) Reunion - 2009

This is a classic from the reunion at Kumarakom in 2009. Compare this photo with the one above.
The only difference is that Meena is standing in front of the group at left side and cracked a joke that only the women understood. (The expression on the men's face hasn't changed from the previous one.) Thresiamma, on the other hand is hilarious.
Can you guess what Meena would have said to generate such response?
