Its the little things that bring me joy

One of my favorite pastimes is scanning craigslist ads. The "free" section in For Sale and "Etc" in Jobs are usually my first stop. I found this little nugget in the "Etc" seciton tonight.

VOLUNTEERS NEEDED

Jock Itch?
Itchy, scaly groin area?
Researchers in the Department of Dermatology at UCSF are doing a study using an investigational topical treatment for jock itch. Subjects (age 12 and older) who currently have jock itch are needed.
Participants will receive either a medicated cream or a cream without any medication in it to put on their affected groin area.
Payment provided.

I'm not sure who I feel more sorry for, the research assist who has to qualify the subjects or the subjects who get the placebo.
