I once pulled out an IV drip cause I hate having needles in my body for long durations, and the thing just spurted blood like Mortal Kombat. I tried to clean it, but it sprayed all over the room and the curtains, there was no hiding my deed. When the nurse came back she was pissed, and I just said "I told you I need it out now or I'll do it myself" as if she didn't believe me. Got my test results immediately after that, suddenly she didn't want me waiting around for another hour.
