To steal one from RFW, I just went to the lady doctor and when she started asking what kind of STD testing I wanted done...
"We tested for HPV and Chlamydia, were you interested in a HIV test as well?"
"Uuuuuum, yeah, that is probably a good idea."
"Okay that is fine. What about Syphilis and Hepatitis? We normally don't check for those..."
I look at her for a moment, sigh in resignation and reply, "Just supersize me."
Luckily she found that funny. Thank goodness for realistic doctors!
