Yee Old Dog Fart.......

Why???? This is all I want to know, why does it seem as though Hoover is so proud of his fart. Then also why do they smell so bad?? Ugh. Oh, one more thing, do you think that he saves them all day till we cuddle on the couch together to watch TV?? Rotten old hound dog farts. I mean whats a Mom to do???
