The best part is the description:
We decided to make a shirt in tribute to one of the first traumatic experiences in life – the visit to the pediatrician. It involves hanging out in waiting rooms with sick kids, toys you're not allowed to play with because other sick kids have been touching them, and an oversized children's Bible as the only reading material for folks under 3 feet tall. When you finally see the pediatrician, he does something to distract you so he can give you a shot, and all you get in return is a lollipop. Not a fair trade. Our 100% cotton black shirt features the phrase "You Never Forget Your First Doctor" under an inexplicable picture of an old-style British police phone box with a white starburst behind it. We have no idea what's going on with that.
About flipping time I make myself a Doctor Who LJ icon, BTW…
EDIT: From the same LJ source, John "Captain Jack Harkness" Barrowman singing "The Doctor and I" (a parody of "The Wizard and I" from Wicked).
