The most fractious of all is Arthur Ramsey (Peter Dinklage), a dwarf with a penchant for strip clubs who is a brilliant mathematician and linguistics expert. "If our E.T. tries to phone home," Molly tells Cavennaugh, "he'll translate the call for us."Hmm... In any case, other disciplines have been equally abused:
- Dr. Nigel Fenway (Brent Spiner), a former 1960's radical and embittered NASA microbiologist.
- Lucas Pegg (Rob Benedict), a meek, somewhat nerdy physicist who reads First Corinthians on his BlackBerry.
