First of all, the burger wouldn't be there after 6 months, or if it was, it wouldn't be in perfect condition - it would have rotted and the burger bun probably wouldn't even be there anymore.
Second, Marty dies whilst chewing the burger for a few seconds. That wouldn't happen. he would at least need to have swallowed it and waited hours until it would get to his stomach and make him ill.
President Monroe's semi-transparent ghost casts a shadow in Mr. Nitzke's bedroom.
Marty DePolo: As soon as I start working my angel magic on you, you're gonna be hanging out with that crowd.
(He points down the hall)
Steve Beauchamp: What, the janitors?
Marty DePolo: No! Look, them.
(The group of janitors move aside and we see a group of students that were standing behind them)
Marty DePolo: Over there. Jordan Labelle and his buds. The cool kids.
Steve Beauchamp: Sure, they're cool now. But where will they be in 20 years?
Marty DePolo: Well, let's see.
(Marty snaps his fingers and everyone freezes. Jordan, the cheerleader and the other guy step forward)
Cheerleader: I'm going to be a supermodel and marry an 80 year old billionaire.
Jordan Lubell: I'm going to be vice-president of the United States.
Guy: I'm going to sell shoes to the vice-president of the United States.
Steve Beauchamp: Wow, they are cool! Except for Shoe Boy.
Marty: I'll do my best God. (Turns to leave but stops and turns back) You are God, aren't you?
Head: Well, um, no. I'm God's cousin, Rod. But I got this job on my own merits.
(After the test is announced)
Jordan: Man, I had three dates lined up for tonight.......and now I have to cancel two.
Kyle: Just thought you should know, you're a dead man.
Marty: Duh! Oh, you mean him!
(After being told he will be Steve's guardian angel)
Marty: Me? I'm sorry, you're making a big mistake. (Starts to walk off)
Head: Hey! We don't make mistakes! (Marty stops and turns back) Well, there was the Bubonic plague......oh, and that awful Chevy Chase show, eww.
Steve: Hey, are you stuck in those same clothes forever?
Marty: Yeah! I'm just like Gilligan!
(Before eating the burger)
Marty: It's not like it's gonna kill me.
Head: Your friend, Steve Beauchamp, is going through the worst time of his life.
Marty: (Sadly) My death.
Head: No, his puberty.
Marty: Alright. I'll give it a shot.
Head: You'll give it a shot. Boy, if you screw this up you will go directly to 'The Other Place'.
Marty: The Mitchell corn place in Mitchell South Dekota?
Head: No, why would I send you to...I'm talking about 'The Other Place'.
Marty: Oh no. Not that!
Head: You might like it. (A red door with 'fire' written on it appears and opens to reveal flames inside) There are lots of rock stars there. (Cue electric guitar music) Hahahahahaha
The Bubonic Plague was also known as the Black Plague. It was disease carried by rodents.
It has occured several times during Europe's history, one of the worst being in the 15th Century.
When Rod refers to 'that awful Chevy Chase show' he is referring to The Chevy Chase Show which aired in 1993.
The fact that the deceased character is named Marty and wears white is pretty likely a nod to the British 1960's TV show 'Randall and Hopkirk (deceased)' or 'My Partner The Ghost' as it was known in the U.S.A which features the Ghost-Detective Marty Hopkirk.
