Whenever someone asks for a must-do, off-the-beaten-path activity in Philadelphia, my first answer is the Mutter Museum in Center City. Few other places in the world can compare to our homegrown museum of medical oddities. But one of the more slept-on aspects of the Mutter is its great gift shop. Its wares are whimsical, often with a sense of humor.

The museum's new hoodie is the perfect example. From the front, it's just your average black hoodie with the Mutter logo emblazoned on the lapel, but the back features a design inspired by 16th-century German artist Alexander Mair that pictures what I'll call the Mutter's "greatest hits."

At the top, conjoined bros Chang and Eng, perhaps the museum's most famous attraction, preside over other famed Mutter residents, like the Cephalothoracopagus monosymmetros (conjoined twins fused at the head and chest), "Widow Sunday" (a.k.a. Madame Dimanche, a Parisian with a 9.8-inch horn growing out of her forehead), swallowed objects, and, of course, the Mega Colon. Seriously, this hoodie wouldn't be worth buying if it didn't feature the Mega Colon.

Like the museum itself, this hoodie is one of kind and can express your love for all things Philadelphia and, well, let's face it, kind of weird. It can be purchased at the museum or at the Mutter's online store.
