I went to target today, and was just browsing. I happened to pass the mens section, and saw some bright colors, so I took a closer look. They were pajama pants. CARTOON PAJAMA PANTS!!! They had spongebob, ninja turtles, and a few others. I only had eyes for the Elmo pants.
I bought a medium (no smalls), and aside from being too big on me, they were well worth $16.
