Boys of a certain age (read, almost any age), have certain favorite subjects.  Body parts and bodily functions.  Son #2 is 7; his filter is not well-developed.  Son #1 has a more developed filter, but has found what he thinks is a way around the system:  Science.  See, apparently, in his 12-year old mind, if you are discussing body parts or bodily functions in the context of something scientific then it's ok.  He's recently been attending a marine biology class during the summer, which gives him additional scientific fodder.
Now put the two of them together.  At the dinner table.  In a public place.
Son #1:  Did you know that the (insert some random name) clam has an extremely long anus?
Mrs. Chako:  Son, is this an appropriate conversation for the dinner table?
Son #2:  An extremely long penis?!?!?!?
Son #1:  I said 'anus' not 'penis' . . .
Mrs. Chako:  #1!  I said not at dinner!
Son #1:  But he thought I said 'penis' not 'anus'.
Son #2:  Yeah, I thought he said penis (laughs at the simple mix up).
Mrs. Chako:  Boys!
Son #2:  But he said 'anus'.
Son #1:  Do you even know what an anus is, #2?
Mrs Chako:  Guys!
Son #1:  Its where your poop comes out.
Son #2:  (Chuckles and shakes his head) Oh.  (Looks at me)  I though he said penis.
Respectfully submitted,
