NicholasW feels no urge at all to apply the irregularity of its homophone to a new (and therefore regular verb).

I feel no need to point out that this is a humorous usage.

I do feel a need to ask NW if he can explain *why it's "the picture was hung" but "the convict was hanged".

I concur on the distaste of splitting the chi and agree with AnnaS (no bias here) that it could be very dangerous particularly in the hands of amateurs.
