Phrase: happy as a clam; happy as a clam at high water

[W Brewer]

GO'T: <<the likelihood of being eaten can make a clam happy too. Imputed

WB:  Sorry, Charlie! His quest for good taste cost Charlie Tuna his sole
goal in life. And just look at a shmoo and it'd jump into yer frying pan.
Seems like a lethal mutation there.
