I actually told this joke about 14 months ago, but figured it was time for a repeat appearance. I hope you all enjoy it as much as you did last time!
So, if you have a dog that loves to go for rides in your automobile and gets really, really excited about it, but whenever you start driving, it gets really nervous, and those nerves manifest themselves with extremely potent gas, so potent, in fact, that you believe your dog is making a mess in the back seat, but when you look back there, there's nothing there... would you say you have a Carpet Shampooer?
(A pet in the car that emits sham poo)
This is funny.
