Hitchhiker's Guide to the Galaxy - What does Arther say backwards?

In the 2005 film, when our troupe gets to Magrathea, Arthur wants to push the infinite improbability drive button to escape the missiles.
Right before he pushes it, it sounds like he says something backwards, like "no solid orc".
Does anyone know what this says forwards?

Thanks!

P.S.
How does one mark questions as "answered"?
I've yet to find some kind of button, and the help files don't seem to point me anywhere...helpful.

search minutes ..i don't know where is it..

<i>The Drive was invented following</i>
<i>research into finite improbability</i>
590
00:42:38,797 --> 00:42:40,753
<i>often used to break the ice at parties</i>
591
00:42:40,837 --> 00:42:43,954
<i>by making all the molecules</i>
<i>in the hostess's undergarments</i>
592
00:42:44,037 --> 00:42:45,993
<i>leap one foot to the left</i>
593
00:42:46,077 --> 00:42:48,511
<i>in accordance with</i>
<i>the theory of indeterminacy.</i>
594
00:42:48,637 --> 00:42:52,027
<i>Many physicists said they</i>
<i>wouldn't stand for that sort of thing,</i>
595
00:42:52,117 --> 00:42:54,153
<i>partly because it debased science,</i>
596
00:42:54,237 --> 00:42:58,071
<i>but mostly because they didn't get</i>
<i>invited to those sort of parties.</i>
597
00:43:07,877 --> 00:43:11,187
ls this gonna happen
every time we hit that button?
598
00:43:11,277 --> 00:43:13,108
Very probably, yes.
599
00:43:13,237 --> 00:43:16,070
Ah, l think
the Earthman's about to be sick.
600
00:43:16,157 --> 00:43:18,910
ln the trashcan, ape-man.
This ship's new.
601
00:43:19,797 --> 00:43:21,515
Come on.
602
00:43:21,637 --> 00:43:24,026
We have normality.
603
00:43:24,157 --> 00:43:25,670
Did it work? Are we there?
604
00:43:27,477 --> 00:43:31,470
Yeah. We're here. Magrathea.
605
00:43:31,557 --> 00:43:33,195
l don't think so. Eddie...
606
00:43:33,317 --> 00:43:35,194
What planet is this?
607
00:43:35,317 --> 00:43:37,035
<i>I'm checking for you.</i>
608
00:43:37,117 --> 00:43:41,907
Did you just pluck
one of my hairs? Off my head?
609
00:43:42,677 --> 00:43:45,396
<i>Thank you for waiting.</i>
<i>Sorry to disappoint,</i>
610
00:43:45,477 --> 00:43:47,468
<i>but this is not Magrathea.</i>

-----------------------

I don't see it myself 0.o

Apparently, it's simply "No, sod it all." but in a weird voice.

Thanks!
