Keen Designs > Comical Shirts > Vestigial Brain
This humorous student humor shirt design says: "Definition Of Vestigial", beneath which is an open book with the details. On the left page are the words: "Undeveloped, Remnant, and Useless." On the right page is an example -- a human brain. Get the point?
If you wear a shirt with this zany design, those around you will get the point, and you'll get a few chuckles.
