Suggestions from the audience

I need a name for a char­ac­ter. He is a sim­ply fel­low, or at least thinks of him­self as such, but when it comes to a sit­u­a­tion of great need he will some­how man­age to save the day and sur­prise even him­self in the process. He is nei­ther inno­cent nor unin­formed. He is in his late 20’s. He can be relied on to keep a secret. He always seems to be there when he is need­ed. He is not afraid to make a fool of him­self. He is brave when nec­es­sary, yet would rather it not be nec­es­sary.
Any ideas for a name for such a char­ac­ter let me know.
