Yes, I understand that it's extremely simple and can probably be done in less than one line. But hey, give me a break! It took me a little while to come up with something slightly clever, and I'm proud of what I managed. Sorry, no ``JAPH'' this time.
And if you're wondering, this was my (also) sad attempt at an ASCII birthday cake.

Constructive criticism is greatly appreciated.
I golfed it down a little and furthered the obfuscation a bit as well, but kept your basic premise. The golfing removes some of the easy readability of your original code garnered by running the likes of:
sed s/eval/print/ mpeg.pl | perl | sed s/eval/print/ | perl | perl -MO=Deparse
Which of course gives us an easy to read, and easy to understand:
@_ = (104, 97, [112, 2], 121, 32, 98, 105, 114, 116, 104, 100, 97, 121, 10);
foreach $_ (@_) {
print chr $_ if not ref $_;
print chr($$_[0]) x $$_[1] if ref $_;
}

?)fer((tnirp\';s,

And I just noticed that my version seems a bit harder to handily pick apart with sed | Deparse (or variation thereof) - the de-obfuscator needs to do a bit more work.
