Setting aside the genetic incompatibilities (chromosome number and disparities in the matchup) how would this physical consummation actually take place? The anatomical differences alone make even the most imaginative configuration highly unlikely, if not altogether impossible.
There may, in fact, be a certain combination of genetic material between a high order of ape (not necessarily a chimpanzee) and some species of swine, but my contention is that it was done by an extraterrestrial visitor, a theory that seems to prevail at the studios of the creators of South Park.
Even assuming the idea that haploid gametes from entirely different geneses could create a diploid cell the resulting cell replication would induce anueploidy which would either be lethal or carcinogenic. Not to mention the bizarre recombination of genes. I suspect this guy has made a drunken leap into stupidity in a manner similar to evolutionists. Perhaps he just saw an old Seinfeld re-run.
