I am weird, the first thing I noticed was the phallic protrusion from the trunk.
As a "joke tree" I would pick it up and go with the protrusion as the "focal point". But a funny tree on my budget is less than $25. I would pass on it. The skill needed to make a "serious bonsai" out of this tree is fairly high, the time needed is likely over a decade. There is easier to work with material to work with out there that is much cheaper.
