ok.. I've stopped being serious... sort of...

what if... err.. what if a baker agreed to do the job but refused to accept the customer's desired artwork
for fear of contravening Sesame Street character ownership copyright.

Seriously, how much more farcial could the situation get
if the gay couple could now be remotely at risk of being sued by Sesame St !!!???😬

That's the trouble, problems can escalate when lawyers and media
start getting involved in a petty, but politically symbolic dispute......
