This thing is getting progressively more difficult to hump effectively.

My people got me this fluffy bed thing last year.  It was pretty okay for napping (soft, fuzzy, warm, etc.), but WAY MORE AWESOME for humping.  I wanted to let everyone know how fantastic this bed thing was, so I would frequently demonstrate its superior humpability for anyone who seemed remotely interested-- and I'll be damned, once I began the demonstration, most people were pretty captivated and impressed.  But... it's getting more and more difficult to get down with it these days, as the bed thing is markedly less firm and fluffy.  It's hard to really get a good grip; maintaining good leverage is nearly impossible... and then there's all the blue fuzz that flies out of the torn seams once I get a good rhythm going.  My People seem a little annoyed by the fluff.  Well, you know what, People?  I'M A DOG.  I'M HAVING A HARD ENOUGH TIME GETTIN' MY GROOVE ON WITHOUT ALL YOUR BITCHING ABOUT THE FLUFF.  Maybe it's time you got me a proper girlfriend.
