Pets are kind of stupid, and pet tricks are really stupid. That is unless you train your dog to flash his junk on command, cuz that's pretty hilarious.

 

I'm trying to think of other awesome things you could train your dog to do, but I'm pretty sure you need thumbs to open up beers and do laundry.  But credit to this dog, showing your wiener is about 29 times cooler than playing dead or rolling over.
