Well, while technically, or biologically, not a father (meningitus at 17 boiled my shrimp) I did recently 'adopt' three strays and their mom; she's an old days acquantance of mine that was in dire straights and I invited them over for a while til she got back on her feet. 8 months later, her three kids (girl-10, girl-13, boy-16) have taken to calling me 'daddy'.
