A tourist who has never heard of Batman or the Joker comes to Gotham, sees the two of them fight, and thinks they're street performers.
They later run into the Joker and tell him they loved his performance and invites him to go drinking. Joker agrees because he's too shocked at the audacity of the situation and he's not going to refuse free drinks.
They ask the Joker if he could invite the other guy as well. Joker tells them he'll show up.
Sure enough, Batman shows up at the bar due to several people reporting the Joker was there. Batman walks in and sees Joker and the tourist casually sitting at the bar. The tourist excitedly welcomes Batman in and offers him a seat. Batman and Joker awkwardly sit on opposite sides of the tourist.
The tourist asks the two of them about their show, how they got into acting, how they met each other, etc. They both give various vague answers.
At the end of the night, the tourist takes a photo with the two of them. They later post the picture to instagram with the caption "I saw these cool performers in Gotham and got a drink with them. I hope I get to see another show some time."
There are several comments that say something like "You got drinks with Batman and the Joker!?" and they respond "Wow. They must be way more popular than I thought if everyone knows them. Are they a traveling theatre troupe?"
The tourist is Danny Fenton
