Apparently an early writer for the show gave Farnsworth the first name Hubert because he took Dreyfus' courses. But, beyond this particular fact, aren't most of Farnsworth's mannerisms quite similar to those of Bert Dreyfus'?
One sees quite the parallel between Dreyfus' wonderful belief in the merits of phenomenology--not to mention the powerful analyses regarding motility and being in the world in general that he is able to elaborate with its help or through it--and the fun Farnsworth has with his Smell-o-scope. Also, they actually do look pretty similar, now that I think about it...
Here is a great interview with Dreyfus, where he talks about coming from the sciences to philosophy, the work of Merleau-Ponty and Heidegger, and teaching (his amazing comments there are in fact probably the least Farnsworthian, who likes to shut himself up in his lab).
Here is a wonderful paper of Dreyfus' on phenomenology in contrast to the (equally wonderful) work of Searle.
And here is a great paper on tele-presence: indeed, if Dreyfus were to go more in this direction, push his thought there, he would end up thinking things similar to Derrida. Cf. his reflections on tele-psychoanalysis in Psyche, volume I, Echographies, and elsewhere. Then again, if you put on anyone's thought you end up with Derrida. Sam Weber (the Derridian) is actually closer to the mark of what Dreyfus there elaborates.
And just for fun is a great picture of Michel Foucault (pictured with students from his philosophy seminar at UC Berkeley, October 1983: the students gave Foucault the cowboy hat as a gift), in an article in which Dreyfus talks about Foucault's visits to Berkeley.
