Peanut says "I'm gonna joust you in the knight hole!" to McSweats. But this was meant for insult.
Pickle says "nobody cuts my Lil Pickle". While is was very suggestive, as Mandarin Chinese refers it as "small penis", but didn't mean that, because Pickle's pet bird is called Lil Pickle.
Pickle twerks when he got a zit on his butt (to show off for more attention). Even Peanut encourages him to do it, just for the fame.
Both P&P admires the wearing of a woman, saying "yoga pants" repatedly.
Peanut shares his kiss to another woman when he has grown up. McSweats shows his body seductively (though it is disturbingly disgusting) to his ex-girlfriend to win her heart back.
Butt crack are always visible throughout the episodes.(especially Pickle's)
