I guess there’s only one name to use when you aren’t using your real name… Smith!
But for all we know this fellow’s real name might be Smith… one never knows in these circles of intrigue… And Dirty keeps throwing money around… other than the contents of the safe, does he have other evil enterprises earning him additional dollars? Sort of like Virtucon, the front for Dr. Evil?
The Daily Trail 
The strip before, Dirty calls him a “young man”. I’m not sure if that was irony or patronizing. I have to say that he certainly doesn’t look any younger than Dirty. Perhaps a year or two older, in fact.
The iguana drawing is much better than the dialog.
