It's bad to sexually harass women.
Glenn is at his desk when Barb comes to work wearing a new, quite tight, outfit that accentuates her body curves.
Glenn wants to tell Barb he loves the new outfit.
Glenn tells Barb that she looks great and that he loves her new look.
Glenn tells Barb that she looks hot, and he's getting extremely aroused and will have to go relieve his erection in the bathroom.
Barb is flattered and blushes as she gets filled with self confidence from Glenn's appreciation.
Barb is horrified that Glenn is objectifying her and disgusted that Glenn is being graphic about his needs.
