For the Fourth of July (Independence Day) weekend, an advertising campaign on the TLA Adult Gay Video site:
(intended: foreskin + independence).
Meanwhile, for some time now the 76 gasoline firm (formerly Union 76) has been running a tv ad campaign against honkaholism (honk + alcoholism, or possibly honk + the libfix -aholism), an addiction to honking.
The first turns out not to convey the intended meaning — an Independence Day sale — very well; foreskins are not centrally involved in the matter, and in any case the term could be parsed as foreskin + dependence.
The second is clever and cute, but becomes annoying on repetition.
