1. Most of Otaku No Video (at the apartment, watching the VHS, at the anime fair, in line while they're watching Nadia, the Otakuland, etc.)
-If you haven't seen Otaku No Video SHAME ON YOU! It has the most Macross references you'll EVER FIND in another animu.
2. I believe Lucky Star has a few Macross references.
-One of the characters (whom I believe is Konata) walks up to the window of a hobby shop. You can clearly see a VF-4 (alike) on the shelf.
