Why does Archer say "Balls" whenever someone says "Benoit"?

In series 2 of Archer in the episode where they go to Monaco, there is a hotel manager called Benoit. Whenever Benoit says his own name, or someone else says it, Archer immediately says "Balls".
I think I'm missing the joke. Why does Archer say that?
Best Answer
Benoit is a French name pronounced like Ben Wa. When Benoit tells his name to Archer, he laughs because it reminds him of Ben Wa Balls, a sex toy.
As the Gran Prix was going on, Benoit checked Malory Archer, Sterling Archer, Lana Kane, and Ray Gillette into a nearby hotel. When Archer asks him his name, Benoit tells him his name, only for Archer to laugh, since it reminds him of Ben Wa Balls, a sex toy.
From Urban Dictionary
Archer: Sounds like 'Ben Wa Balls,' Benoit... Balls. See? You can't even say it without saying 'Balls.'
Archer: Hang on! Benoit Balls!
