The common idiom for this kind of loop is to have the raw_input at the
end of the loop:

input = raw_input("Who goes there? ")
while input != "Chris":
    count = count + 1
    if count > 1:
      print "You have fondled my keys", count, "too many times!"
    print "Please move away from my machine!", input, "!!"
    input = raw_input("Who goes there? ")
print "Chris, ...

This probably does what you want.
