In the season 3 episode where we meet that giant 7 footer too tall jones and arnold is feeling like a looser so he goes outside on the high building arnold was halfway back to safety and drummond shouts out dont look down then arnold looks down and gets scared, drummond should not have said anything because him too tall had save arnold from falling from the building lol.
