David S Day 13

 3/6. Was sure I had 2 and thought I might have had 4. 

1. MacArthur :), D11. Gimme. 
2. French Laundry :), D00. Cute question. I was certain here. 
3. I’m Yours :(, D33. Zero clue. 
4. Major :(, D23. Too bad. I knew it was an M. Didn’t know what it stood for. I assumed it was an adjective for no good reason. 
5. Slip rhyme :(, D22. No idea. 
6. Sap :), D11. I questioned whether this was right because it seemed too obvious. But I didn’t have any other guess.
