When Robin Met Superman - Dick, Jason & DCAU!Tim.
I think it's been established that there are a lot of Superman fans in the DCU. A lot of people wear the t-shirts, love autographs and generally wanted to be Superman when they grow up.
I decided to post this when going through some old issues, I realised that a few of the Robins get thoroughly excited when meeting the man for the first time. These are from Legends of the DC Universe #6 , Action Comics #594  and Gotham Adventures #36 
Let's start with Dick from Legends of the DCU #6.
Sometimes, Superman needs a Robin too.
Let's move on to Jason, who is really enthusiastic, so much so that I almost thought this was pre-crisis!Jay.
Don't worry, Batman. You'll get a Batman Day soon enough.
Now here's where things got tricky. I tried looking for Tim's first issue with Superman but sadly, the earliest I could find, they already seemed pretty familiar with each other, so I'm not sure if it was their first meeting.
