T-shirts with humorous messages on them are everywhere nowadays.
Here's one I saw on the UF campus here in Gainesville the other day. (It takes a little math background to get the joke, but with all the math and engineering guys here, I bet it will get a chuckle). /www.google.com/search?q=be+rational+get+real+cartoon&tbm=isch&source=iu&ictx=1&fir=izAadp72ic2HfM%253A%252CqpsVsvrhD8ZLDM%252C_&usg=AFrqEzdT7GvC14HqzEMMg8JxTWUPvKhUQQ&sa=X&ved=2ahUKEwiI2-fcvZfdAhUQd6wKHfyzCZAQ9QEwBXoECAYQDg#imgrc=izAadp72ic2HfM:
Seeing that shirt inspired me to do a little "funny t shirts" googling just for fun, resulting in my finding a bunch of really good ones. Here's another one: /www.google.com/search?q=t+shirt+sodium+cute&tbm=isch&tbo=u&source=univ&sa=X&ved=2ahUKEwin1P71wZfdAhUHcq0KHQH_AtsQ7Al6BAgGEA8&biw=1280&bih=578#imgrc=XthQh5lIKEC-VM:
So if you have a little time, it might be fun to google this topic yourselves, and get a laugh out of some of the funny t-shirts you find, especially the ones in math and the sciences.
