Considering most voice actors are grown-ups, this is actually pretty common for VAs to vulgarly joke around in voice recording sessions.
In the Garfield "In Dog Years I'd be Dead" anniversary book, one photo featuring "Garfield & Friends" guest star Buddy Hacket said he was in the middle of telling a really dirty joke.
Gilbert Gottfried & Robin Williams supposedly sometimes slipped and said adultish things while making Disney's "Aladdin."
Even on the Sonic the Hedgehog SatA.M. "The Complete Series" DVD set, there's a special feature (maybe an easter egg, I can't remember) where Jaleel White (Sonic's original voice) was asked what the hardest thing about voicing in animation was. He said while chuckling, "Trying not to be as vulgar as everyone there in the studio wants to be."
There's also some blooper/gag reels on Youtube of old kiddy shows like "Zoobilee Zoo":https://www.youtube.com/watch?v=QIE0FT89m40 where the people making the shows joke around rather vulgarly, as well. Just look at this "1972 kiddy show.":https://www.youtube.com/watch?v=fOAgATcn_yY (Warning language/suggestive.)
Making kid shows must be alot of fun.
