Their are numerous times where we the audience get to see steve urkel make a fool out of himself by falling hard on the ground like when a girl kisses him or he is about to get get kissed by a girl for example the episode where steve bribes laura into going out with him to a concert if he can bring a celebrity singer to the house to meet her, before laura could kiss him he faints and falls down at random lol, did steve urkel get nervous which caused him to faint or do you think he just got a hot flash which caused him to faint ???
