3rd Rock From the Sun?
So, there's this team of advanced-civilisation individuals put in present-day human bodies who have to deal with their present-day lives -
we've got the oldest member of the team in the body of a high-school kid,
some military hard-ass in the body of a young woman, mother of an infant at that, to make her more vulnerable,
and a team leader who has a goofball kind of vibe about him (or is it just Eric McCormack's vibe)..
I dunno...
