Execute prints backwards

Commodore 64 BASIC

40 print "Line 1"
30 print "Line 2"
20 print "Line 3"
10 print "Line 4"

PHP

Abusing precedence... :-)

!print "Line1\n".
!print "Line2\n".
!print "Line3\n".
!print "Line4\n";

C

Undefined behavior is the most exciting kind of behavior!

f(){}
main()
{
   f(printf("Line 1\n"), 
     printf("Line 2\n"), 
     printf("Line 3\n"), 
     printf("Line 4\n"));
}

Actual output may vary depending on your compiler, linker, operating system, and processor :)
