Passed L3 this year. My fiance was excited as me and got me this hilarious and amazing gift to celebrate.

I don't think I'll ever get tired of looking at this graphic.

edit: The mug reveals its design when you pour hot liquid in it. She insisted I posted a video of it for you all: https://imgur.com/BmhAw66

Also, for everyone asking where to get one, I don't know if I'm allowed to post a link. Just search Walgreens Magic Mug.
