Even though the concept of Doug running into Ray is possible, it is unlikely that it would happen in a supermarket. On Raymond, the Barone's address was on Fowler Ave in Lynbrook, NY. In Lynbrook, there is a grocery store on Hempstead Ave called Cross Island Fruits. This is where the Barones would most likely do their shopping. Since the store is located a good 15-20 minutes (depending on traffic) to anywhere in Queens County, it seems odd that Doug would shop there.
In the flashback, Carrie/"Simone" looks 8 or 9. Wouldn't you remember that your name was changed from one to the other? It's not like she was a baby in the flashback.
We learn Carrie's real first name was Simone. Arthur lost it in a poker game.
Ray: (looking in Doug's shopping cart) Log of salami, chips, and cheese—so you're not buyin' into the whole cholesterol thing, huh?
Arthur: (to Carrie) Are you happy with your life, schlepping coffee for suits by day and folding giant underwear at night?
Carrie: I'm going to New Jersey with my father to visit my mother's grave for the weekend.
Doug: (trying to stifle excitement) You're going to be gone for the weekend?
Carrie: Could you at least pretend you're going to miss me?!
Doug: Let's shake things up a bit.
Ray: You wanna get a pizza?
Doug: No! Well, yes, I do. But that's not the point!
Doug: What's wrong with "Kettle Korn"?
Ray: It's not organic. It doesn't come up in a sentence much.
Doug: It does for me.

The German episode title is "Wilde Bullen", meaning "Wild Bulls".
While watching TV with Doug, Ray comments it'd be awesome if there was a nail gun fight. This slyly refers to Ray Romano's appearence on The Simpsons episode "Don't Fear the Roofer", where his character, Ray Magini, had a nail gun fight with Homer Simpson.
Episode title is a nod to the movie Raging Bull.
