if you do this:
var fun = function(){console.log("lol")}
nothiong's gonna log since we only define fun but we don't call it. So why is this executed?
var request = http.get("http://teamtreehouse.com/" + username + ".json", function(response){ console.log(response.statusCode) })

In the above code, you're assigning a function to a variable, and you're correct, it doesn't execute until you invoke it using fun()
var request = http.get("http://teamtreehouse.com/" + username + ".json", function(response){ console.log(response.statusCode) })
This line however, you're NOT assigning a function to variable request , this line is kinda long and messy, perhaps if we simplify it a bit, it'll help you see it more clearly.
var request = http.get("do something");
Which is similar to this following line.
var number = Math.abs(-3);
It's just a method call on an object then assigning its value to a variable.

Courses Plus Student 26,868 Pointsok, that's not a good example, I updated it to use Math.abs() instead, hope it makes more sense.
