Doogie Howser, M.D./YMMV


 * Hilarious in Hindsight: The very same episode that tells us homophobia is wrong has a plot which ends with Doogie being informed by his girlfriend that "[his] charm lies in not being one of the guys."
 * Also Doogie attempting to drink scotch and smoke a cigar, but getting ill. Years and years later on "How I Met Your Mother", he's playing Barney Stinson, who smokes cigars and is a functional alcoholic.
