It was always funny when doing group assignments folks would join me thinking I would do the work because I attended most classes and got decent grades. Especially those with a last chance of making it often tried to benefit from my work.
And then they would be like: "Wait, that assignment is today? Sorry, I was busy and my goldfish/grandma died. What do you have for us, another A+ project I bet?"

And I would be like: "I haven't done shit"

"If we don't pass this class, I really can't afford doing another year. You're joking right, you must have something?!"

My degree took me 18 months longer because I was having too much fun ruining the freeloaders and didn't think they were 'worthy' of my work.
