I know these guys. You misheard them -- it's Ken and T-Bone. T-Bone is a nickname, but it's what everyone calls him and is basically his real name.

One of these guys (the one with the dark hair) is a regular at JVs, or used to be. And he goes to Hanks whenever a friend's band is playing.

I've known these two for 20+ years. Both in their mid-50s, one with dark hair (maybe a pompadour depending on the night), and one bald with white hair -- right?

It's not a scam, just a drinking/social lubrication game that they've been playing some version of for decades. They're nice, friendly guys. Promise.

The typical questions are last digit of social security (precisely because it's mostly random, unlike the first number), age ears were pierced, last time you got a haircut, what time you woke up, number of siblings ("no halves or steps"), last time you were on an airplane, age of your first "real" or "intimate" kiss, age you first started driving, etc.

If no one will play the game with them, they'll move on to the bartender or just play rock/paper/scissors among themselves.

tl;dr: hoofbeats, horses, zebras.
