(This is pure silliness)

About a week ago, I was feeling happy for no particular reason and so I put "Andrew is happy as a clam" on my Facebook status. Then, a couple of days after that, I got sick, so I thought I would write "Andrew is sick as a dog", but at the last moment I decided to write "Andrew is sick as a clam" instead. Then, later in the week I felt a bit better, and thus "Andrew is as happy as a somewhat sick clam". (Followed, for the record, by "Andrew is as happy as a somewhat sick clam who's full of barbeque", "Andrew is trying not to be shellfish", and then "Andrew feels as healthy as a clam!".)

The point is that the phrase "sick as a clam" just amuses me no end, and I can't even quite figure out why. I know this can't amuse anyone else as much as it does me, but I still want to twist a few other common animal phrases ("clever as a fox", "strong as an ox", "proud as a peacock", and so on).
