Always make sure I'm standing next to my DH if in public, which is almost like blaming it on the dog!
or we'll blame it on the loose floor boards. barking spiders. Or.... a joke with my dad (had to be there) it's his deer call, he'll let it rip and say "here deer". (which of course prompted me to buy a fart machine w/remote, and tape it to his hunting blind chair one season... he he he!)
One of my dad's friends owns a liquor store, and he's got a huge scary-looking Doberman. The dog is a complete sweetie-boo, but the visual effect is good. The dog sleeps in a big easy chair by the cash register.
The guy got one of those remote fart machines and crammed it under his sleeping dog.
Watching him set it off while a customer is checking out?
Priceless.
