Subway ad-Sci Fi geeks discuss new grilled cheese, tomato an

First post, please correct if this is mis-usive of the site. There*s a great ad currently running here in the States that features a couple of geeks talking about the new Subway grilled cheese,tomato and bacon sandwich. The two sci-fi obsessed characters argue, in unknowable language, about comparing the sandwich to a grilled cheese is like (something like this) "saying the Brehton Gh*re is an apprentice to the Dul Graboo". Then they laugh in way way that reminds me of whatshername that used to play The Nanny on the TV sitcom. The question I have is, what do they REALLY say? Is it based on a real sci-fi commodity that I*m not hipped to? I have tried to a wild extent to contact Subway and Googled til my fingers cramped but can*t find out any info on this ad. I think these two characters could be exploited hugely. Anyway, thanks for any info anybody has out ther
