That's understandable and awkward but at the same time there are condom, enzyte, tampon, beer, and many other commercials on tv at all hours of the day that would need explaining too. For that matter there are many basketball games where a cuss word slips through on broadcasts that might need explaining too. I have actually had to explain to a kid once what why the guy in the Enzyte commercial was always smiling. Very very awkward but it happens. When they are that young it is best to just say "that is a commercial for adults". After a very vague explanation he gave up. Ha
