Urine For A Shock

(I work as a Drug Tester, doing supervised urinalysis for the state. I am male, but I get male and female clients. When I get a female client I have to get a female coworker to do the supervision. I am admitting a brand new female client and call one of my coworkers down.)

Co-worker: *after doing the test and sending the client on her way* “That was the
most awkward urinalysis ever.”

Me: “Why?”

Co-worker: “That was my boyfriend’s ex!”
