There was a CL post making rounds earlier about writing the most "wicked" hello world program.
Here is my response:
r,e,a,l = range,enumerate,all,0 for i,x in e(i for i in r(4,10**4) if a(i%j!=0 for j in r(3,i))): if not 01225064762735104601006456677135667000644077661030607%x: print chr(i-l), l=i
It works by factoring that large number into its prime factors, then taking the distance between the prime factors and converting the distance to ascii characters.
