...that bird.lol comics are brought to you under a creative commons 3.0 license? Are you editing a non-commercial publication (student newspaper, info flyer, etc.) that could benefit from a bit of humour? Just stick a bird.lol comic in there. You don't even need to ask. (By the way, if you want to do something that conflicts with the license or are not sure, do feel free to ask me!)
Prof. O lecturing.
O: Welcome to the lecture “Imaginary Adventuring II”. Before we start, please do a perception roll to see if you are actually here.
G and H are attending the lecture. They both have dice in front of them.
H: What?... alright ... nope, failed. Well, guess I’m trying again next semester.
G: Yeah! Critical success!
G awakes in their excellence box.
G: Oh. I see. Well, I could’a guessed. That lecture was far too much fun to be actually a thing.
