It finally looked hard enough, I'm so proud of it

A few weeks ago I was in a hotel and got room 404. I was very close to going to the reception and tell them I couldn't find it. 

My GF was there though so I didn't, lol. 

the last 2 times i was in a hotel i was given room 404

and my name in class kahoots is "404-<name> not found
