: : : : Hey all. I've heard the phrase "This ain't my first rodeo" used here & there but I didn't see it on the list. Meaning/Use (derived in context but rather obvious): Usually in construction when someone feels they are being "instructed" below their level of comprehension, eg a carpenter with 8 years experience being told how to plumb a doorway or what-have-you. I thought I'd recommend it for the list here.
: : : It's a good one. The first time I heard it was in "Mommy Dearest" said by Joan Crawford.
: : A British version is 'I didn't come down with the last shower'. Is this used elsewhere?
: James, an equivalent, "I didn't come down with yesterday's rain," is used in the U.S., but not on the same kind of occasion as described above. It means "I'm not naive; you can't fool me that easily." ~rb
"I wasn't born yesterday" is another related one. Pamela
