Get the Half-lifemug. I have worthless gas station people telling me "I'm fine" and whether or not I'm fine is irrelevant. I'm not claiming being un-fine. I'm claiming being the creator or A.I. and not being paid. And it's a problem of child murdering purportion.

Get the Your life is shitmug. Another turning point, a fork stuck in the road
Time grabs you by the wrist, directs you where to go
So make the best of this test and don't ask why
It's not a question, but a lesson learned in time

I hope you had the time of your life
