As my buddy, mcapo, wrote in another thread, the self-depreciation (even intended as humor) has run its course and lost its value.
Stand tall and proud, and yell "I am doddg, hear me roar" !
1. I remember reading that now that you say!
2. All right: no more self-deprecating humor, but it is my default, testing people to see if they will believe it, just to have them find out from somewhat else: "He's kidding you!"
3. I do love your humor, though, in your second line.
