I think the hardest / longest has to be from Holoship...
Rimmer: Just thinking. Assuming of course we're not dealing with five-
dimensional objects in a basic Euclidean geometric universe and given
the essential premise that all geo-mathematics is based on the
hideously limiting notion that one plus one equals two, and not as
{Astemeyer} correctly postulates that one and two are in fact the same
thing observed from different precepts, (Loudly breathes out through
his nose.) the theoretical shape described by {Siddus} must therefore
be a poly-dri-doc-deca-wee-hedron-a-hexa-sexa-hedro-adicon-a-di-bi-
dolly-he-deca-dodron. (Loudly breathes out through his nose again.)
Everything else is popycock. Isn't that so?
