My two newest additions to my list of hot/cute "idiot box" geeks, although I don't watch that much TV..
Ivy leaguer with radical honesty, Lightman's researcher Eli Loker (Brendan Hines) of the newest Fox hit series, Lie To Me.
John Francis Daley, Bones' Dr. Lance Sweets. His witty barrages with Booth (David Boreanaz) in the series make said TV show more adorable, and he really look sweet. *chuckle*
