I think that “Very Exciting...Very Dangerous,” is a great catchphrase. Of course, it can be punctuated however is preferred. If it ends up being a “keeper,” it may be fun if the respective first guests would pronounce the catchphrase however they fancy.
Keeping a catchphrase, again of course, comes with the repercussion of using it instead of working through the list of suggestions for the duration of its use.
Thank you for your consideration.
