Well, Mr. Potato worked out on his treadmill.

And napped. A lot.
Then the poor guy was left home while I went to pick up a friend for drinks/dinner. Usually, when I am over there, I bring Mr. Potato. I asked her if I should bring him over so that he could hang out with her dog while we were out.
She paused. And a realized what she was going to say was no and that it made sense. Mr. Potato annoys her cat, who spends the entire time hiding while he is there. And he annoys her dog, who doesn't want to play with him.
So, Mr. Potato, the poor fella, stayed home. He is now sleeping next to me, on the recliner, happy as a clam, though.
He is just so....intense. He is too much for other dogs (unless they are young or hyper)....and definitely too much for cats...
At least his Daddy (and grandmother, and every other human), loves him.
