Today's revealer is suggested by the puzzle's circled squares, in which we find one P where two would normally be expected - literally, TWOPEASINAPOD (the pod, in this case, being the crossword puzzle square). For example, we have VI[PP]ASSES crossing everyone's favorite, the WHO[PP]ERJR. The revealer's clue "Almost twins ... " puts me in mind of a thing that happened to me and my younger sister when we were teens. We were at a hair salon, and a woman asked us if she and I were twins. We said no, and she said, "are you sure?" We thought it was a RIOT.
In other amusing AERIEas, I enjoyed the apt C/AP "Betting game in which you could lose your shirt" (STRI[PP]OKER). Apt! I also enjoyed "What might be taken to go?" (EXLAX). We don't often see NYTX constructors working the poo material, but I thought this was a gas.
I liked what I construed as two crossed Simpsons references, TORI ("Doughnut shapes, mathematically") mmmmm, donuts... and DOH ("[head slap]"). I also liked ROT, LYCEES, MACHONE, and PONCHO. I enjoy thinking of real life situations in which people might actually say, OHO, and who doesn't like NERDS?
Not being a big sports fan, and knowing very little about the NY sports scene, I thought there was rather a lot of 'nets and jets' (THENETS ; NYJET), but as this is the NYT crossword puzzle, I'm going to have to LEGATO.
