Guest star Pat Morita and series regular Al Molinaro would go on to roles as the owners of Arnold's Drive-In in Happy Days, with Morita as "Arnold" and Molinaro as his successor, "Big Al."
This episode contradicts "The Odd Couple Meet Their Host," where Oscar said Felix was a prisoner of war in a German camp. Here, Felix served in the Pacific theater rather than the European theater.
Felix was a second lieutenant at Guadalcanal.
Yamata: I think I get real silent partner. Maybe Howard Hughes.
Felix: How'd you get lost?
Yamata: I was kamikaze pilot. I got nervous and make safe landing.
Felix: Why didn't you go back?
Yamata: They only gave me one-way map.
Yamata: (at Guadalcanal) Don't believe everything you hear. They told me I'd be making love to Betty Grable on White House lawn by Christmas.
Yamata: I have a takeout tray that is dynamite with the college crowd. They think it is hip to eat Nip.
Yamata: Mr. Unger a very fine gentleman. In Japan, he would be considered most honorable man.
Oscar: Over here, he's considered a pest.
Felix: This is the authentic Japanese cooking. They prepare the food at the table.
Oscar: Can't they afford a kitchen?
Felix: I invested it.
Oscar: In what?
Felix: In something as solid as the Rock of Gibraltar and rooted in the basic needs of the American people.
Felix: A Japanese restaurant.
Murray: I wish Felix was my best friend.
Oscar: How do you want him, dead or alive?
Murray: I never bet on the ponies. There's only one sport I bet on.
Oscar: What's that?
Murray: Professional wrestling.
Felix: How dare you?
Oscar: How dare me?
Felix: To accuse me of pilferage for personal aggrandizement.
Oscar: Well, what did you do with the money, gave it to nasal research?
Although Pat Morita's character is called "Yamata-san" all through the episode, the end credits credit Morita as "Mr. Wing."
Oscar calls Murray "Tokyo Nose," after the infamous World War II Japanese broadcast propagandist, Tokyo Rose.
