Short form and what to use

I have a question regarding usability and design of forms. When having only two options in a drop down list with a very limited amount of real estate available what is the best title to use.

i.e. I have a drop down select box with only two options - Yes & No normally I use the "Please Select" as the title, but on this occasion the real estate I have available is limited and would prefer to use a shorter form of a title, but what?

Question: what do you use when your selection has a very limited amount of text in it, where you also have the requirement for a title of some sort to prompt the user to select at least one?

With thanks in advance,
