It should be "are"

My spelling and grammar are
My spelling and my grammar are
They are

Those three segements are equivalents.

For some very odd reason, possessive subjects seem to confuse people when it comes to verb agreement.  If a list of items can be consolidated as one single "thing" then sometimes it can operate in a singular form (and I'm trying to think of an example but one escapes me), but usually it's plural.

The grammar issues that I see most frequently online and subsequently irritate the hell out of me:
-Then and than.  Then = Condition, Than = Comparison.
-Your and You're.  That's just laziness people.  You learned compound words in grade 1, for Pete's sake.
-It's and Its.  It's = It is, the verb "to be."  Its = possessive.
-Affect and effect.  Effect = noun.  Affect = verb.
-Their, they're, and there.  If I need to explain this to anyone they'd best not tell me
-Who and whom... though this is less of an issue in informal English.
-Irregardless.  Don't ever do that.  Ever.

I had no idea that this thread was actually about the grammar inquisition arresting people.

I guess that explains why it's Goober in the picture.

I prefered it when he was called Gooby

Hehe =)  Only problem is, the comic is using it improperly.  Effect is only a verb when used with an object.  "The situation" in that sentence doesn't really qualify (depending on meaning; I suppose you could be extremely obscure and say that it brings "the situation" into existence but that's a really archaic/obsolete form, beyond simply obscure).  That sentence should actually use affect.  Now, you could say "Our foreign policy has effected a change in the situation" and be entirely correct.

Obscure grammatical references aside, the affect/effect thing really gets on my nerves, though then/than still tops the list

I doubt that that's actually Goob. No name, no info, just some guy with a nametag that says "Goober". there could be dozens of people with a pair of coveralls with "Goober" on them. The only confirmation we can get is from Goob himself.

Somehow I don;t think Goober got a master's degree in CS to become a janitor...

I was going to post something about him being too smart or whatever, but I wasn't sure where or what he worked at.
