I know a 58 year old guy who still likes to cruise local non-college clubs to dance and have a drink or two to flirt with women, and recently he was taken aback when he was re-entering one club after a smoke break and some young girls were blocking the entrance. One girl in the group saw that he wanted through and then said "Let grandpa through" which made him feel like a loser.

What are some witty responses an older gentleman could use on such an overt attack? I've been thinking of a couple here using A&A:

"That's great grandpa to you" (smirk)

"It's times like these I'm reminded of the old saying 'men age like wine, women age like milk' (smirk)
