When I lived in New Jersey, I'd sometimes visit my sister in NYC and usually we'd hit up a comedy club. One time, Jim Gaffigan wandered in and did 10 minutes, totally killed it.

During his set, he mentions that he's a regular person and just wants to be treated the same way we'd treat any of our friends. I gave him a high five as he exited near my table.

A couple weeks later, I see him walking down the street, I say "hey Jim!" And he responds "hey..." like he was confused why he didn't know me. The next time I saw him randomly on the street, I asked if we're still on for lunch on Tuesday. He stopped walking and asked "what?" I kept waking and shouted, "great! See you on Tuesday!"

The following Tuesday, I made no attempt to see Jim Gaffigan for lunch the same way I would for any friend who didn't give me their number or make a true attempt to confirm plans.

After my dad died, I moved back to Texas and haven't seen Jim Gaffigan since. So now I talk shit about about him behind his back like I would for any unreliable friend.

Tldr: had three brief interactions with Jim Gaffigan, dude is incredibly patient and pleasant. 10/10, would invite him to lunch and not show up again cuz he's an unreliable asshole of a friend.
