Echo the following in as few bytes as possible:

I'm Slim Shady. Yes, I'm the real Shady.
All you other Slim Shadys are just imitating.


The following five words must appear EXACTLY ONCE in your code:

I'm
Slim
Shady
real
stand

# C, 374

By moving memory

Not the shortest but can it get any faster?

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
char *s;
void m (int d, int f, int p)
{
memmove (s+p+f, s+p, strlen(s)-p+1); // Shift a part of the string to make room for our insertion
memcpy (s+p, s+d, f); // Copy the desired reference in place
}
int main ()
{
s = malloc (168);
strcpy (s,"I'm Slim Shady. Yes, the real.\nAll you others are just imitating.\nSo, won't the please stand up?\nP. ");

m (0, 4, 21);
m (8, 6, 33);
m (3, 11, 54);
m (28, 5, 100);
m (3, 11, 105);
m (118, 14, 135);
m (134, 16, 151);
puts (s);
}


It's 374 chars long after minification.

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
char*s;void m(int d,int f,int p){memmove(s+p+f,s+p,strlen(s)-p+1);memcpy(s+p,s+d,f);}int main(){s=malloc(168);strcpy(s,"I'm Slim Shady. Yes, the real.\nAll you others are just imitating.\nSo, won't the please stand up?\nP. ");m(0,4,21);m(8,6,33);m(3,11,54);m(28,5,100);m(3,11,105);m(118,14,135);m(134,16,151);puts(s);}

• Nice, but you can golf it down to 278 bytes: char s[168]="I'm Slim Shady. Yes, the real.\nAll you others are just imitating.\nSo, won't the please stand up?\nP. ";m(d,f,p){memmove(s+p+f,s+p,strlen(s)-p+1);memcpy(s+p,s+d,f);}main(){m(0,4,21);m(8,6,33);m(3,11,54);m(28,5,100);m(3,11,105);m(118,14,135);m(134,16,151);puts(s);}

Now with Proper Capitalization and New Lines

• You could probably save some more chars by moving spaces from format string to replacements, like WriteLine("{0}{1}","I'm ","Slim "). Aug 2, 2014 at 0:09
• The ending newline doesn't seem to be a requirement, so consider using .Write() instead of .WriteLine(). Even if it's required, .Write() with a \n is shorter.

Java is a bit verbose, but here is my try:

class P{public static void main(String[]c){String s=" Shady",t=" the real",l="lease stand up",i=" Slim",m="I'm";System.out.format("%s%s%s. Yes, %s%s%s.\nAll you other%s%ss are just imitating.\nSo, won't%s%s%s p%s?\nP%s. P%s.",m,i,s,m,t,s,i,s,t,i,s,l,l,l);}}

• You can 1-merge 'real' and 'the', they're always together 2-move some blanks out of the big format string 3-above all: use more single variables, the a array is of no use. All in all you can go to ~270 Aug 1, 2014 at 21:05
• @edc65 I didn't know that I could declare multiple strings in Java without writing String multiple times. That's why I had the array for all but one variable. Thanks a lot for the hints.

This one is impressive since simply printing the text is more efficient, but this is way cooler.

Not that good but might as well post an answer.
