I bullshitted my presentation today in anatomy and physiology class today without a poster or anything, and my explanation of the urinary system off the top of my head was essentially this.

Me: "…and then the waste funnels into that thingamajigger."
Teacher: "You mean the renal pelivs?"
Me: "Yeah yeah that's the one; then it goes from the renal pelvis to the… uh…" draws imaginary lines over abdomen "the whats-its here."
Teacher: "…You mean the ureters?"
Me: "Yeah the ureters."

And it went like that for about five minutes.

Joss Whedon, your Buffy-speak antics have doomed us all.
