Not all your suggestions will work, and on this page explains why.
If someone else can make it work, they will share credit with you.
Lewd and Viewed are not using the same sounds:
Very good inspiration, but "punt" and "cunt" do not have the same sounds.
Full suggestion: I love my pet wussy. RT if you read that wrong. Sorry but this one does not quite qualify, as this is simply a spoonerism with a made-up pet name. It would work if this was an existing, famous or ordinarily or frequently used, pet...
"Balls" and "hole" do not actually match phonetically, so after checks were made, this can no longer be approved, we fear. But it can surely be salvaged, as this is a very good "topical" one!
Technically this cannot be accepted as the switch of sound is "impure": the switch is between a "g" and "fl", giving a fusion of "fl" and "l"...
Jelly Bean > Billie Jean Sorry but this one does not qualify, as the pronunciation of the vowels do no mqtch. dʒɛli bin > bɪli dʒin Can an,yone salvage this one? Maybe plqying with Jocks/Box dʒɑks, bɑks dʒin, bɪn
Bagots cannot fend for themselves without Bilbo. > Faggots cannot bend for themselves without dildo. Sorry but this one fails on all accounts, and if it is salvaged it will probably no longer relate to Lords of the Rings, which is a pity as it...
Sorry but this one does not qualify, as the pronunciation of "good" and "prude" are not the same. Close, but different.
Can anyone salvage this one?
Again it may work as a spoonerism but not as a contrepeterie. It has all the ingredient for a good contrepet, but the result "all his sight" does not work as a meaningful sentence. And the "sight" has no impact: it is not rude or politically meaningful. (Think about updating it for the next presidential race to Romney)
Another case of a spoonerism that does not qualify as a contrepèterie.
The pronunciation does not quite work. The phrases do not stand on their own, and they do not work together. And it does not mean anything really!
It is famous, it is funny, it is a successful spoonerism, but a failed contrepèterie: either most people will pronounce it "arses"; or if pronounced "asses" then the r is just dropped/fused, not switched.
