I stupidly put in COP PORN for 1D, despite the enumeration not fitting, and that slowed me down a bit. Love to see bookending Spoonerisms, though, especially since they were both clued differently.
5A made me laugh at ["Woke Tapir" insiders], very good, and 4A was my favorite with that definition of [a common bank form]. I also thought [articulated joints] was cute in 7A, and the [dropping E] in 2D. I had fun!
