JISM T-Shirt

The Jordan Institute for Standards and Metrology sounds like a legitimate government organization for about half a second — until you realize it’s a ridiculously dirty shirt. Styled like a prestigious official logo, this design is peak immature humor — perfect for anyone who loves naughty jokes and pretending to be part of an organization dedicated to measuring. It’s subtle enough to wear to work, but filthy enough to make people not like you.
