- 18A: Kind of nut (KOLA). I saw a tweet the other day from someone who mistyped KOALA as KOLA. It ended up making the tweet pretty funny but it would be totally inappropriate for me to share it with you here. Sorry.
- 24A: 2011 Rose Bowl champs: Abbr. (TCU). Texas Christian University. Their mascot is the horned frog. And I thought being a terrapin was lame.
- 50A: Disco __ of "The Simpsons" (STU). Not being a Simpsons fan, I used to have a hard time remembering this. It helped for me to learn a little something about the context, so I'm going to pass it along to you in hopes that it will help you as well. Now I'm sure I don't have all the details but apparently there was a jacket that was being customized for Homer that was supposed to say "DISCO STUD" on the back. But they ran out of room and it ended up saying "DISCO STU." So now you know. (If you didn't already.)
- 7D: Western necktie (BOLO). I have to say that I really do miss living in a place where you see men wearing bolo ties and/or cowboy hats as just a normal everyday thing.
- 29D: Architect Frank __ Wright (LLOYD). Weren't we just talking about him yesterday?
- 47D: Stay out of sight (LIE LOW). I know this is grammatically correct, but I'm pretty sure I've heard people use the incorrect "lay low" more often.
- 54D: Robert of "The Sopranos" (ILER). Runner-up for today's Crosswordese 101 entry.
- 57D: Nick Charles's wife (NORA). Pop quiz for anyone who's just starting out on crossword puzzles. What's the name of Nick and Nora's dog?
- 60D: "For Pete's __!" (SAKE). This is funny but I can't tell you why yet.
