During a scramble for bunk choice while arriving in Iraq, I left a duffel bag on a bed I wanted. I came back to find, scrawled on the bottom, “I told you this was Jimmy and I’s room!”
It’s still there, as a permanent reminder that other people are stupid.
b) But it’s still “whoever”, so the OP stands. I called it a predicate nominative because I read it as “Dad is whoever”, not “whoever is Dad”. As in, “Mom claims (that) Dad is whoever (or Jim, or Bob).”
Take the statement “It’s Jim that Mom claims Dad is.” vs “It’s Jim that Mom claims is Dad.”
c) I had to Gaudere myself because I’m a law-abiding Internet citizen.
I claim 4/5 points. You have insulted my honor. Whaddaya say, pistols at dawn?
Fucking Handle…ooooooooh…
Whom dat? Drew dat!
Since I was intentionally trying to use “proper” English when I wrote that, I guess I’ll have to concede your correction. I just hope my OCD doesn’t make me obsess about that later.
