When you are in the process of editing a theme it will display the custom theme you are editing to you and you alone until you close the theme editing window or save the custom theme. Anyone else browsing your site would see the active crazy theme.
Open another browser besides the one you are editing the theme with to see the true active theme, or close the theme editing window and it should start showing you the theme that is active rather than the custom one you are editing.
If you close your browser and re-visit the site this will also clear your session and allow you to view the same theme your customers see.
