You know Disney; the "Good teenagers take off their clothes" in Aladdin, the Rescue Rangers sex scene (through a fleetingly seen window), the penis in the poster for The Little Mermaid… The Lion King already has the most blatant one with the stardust spelling out "SEX" in the sky!
But is this more innuendo I spy in Hakuna Matata? The lyrics are:
"I’m a sensitive soul though I seem thick-skinned,
And it hurt that my friends never stood downwind
And oh, the shame…" "He was ashamed"
"Thought of changin’ my name…" "What’s in a name?"
"And I got downhearted…" "How did ya feel?"
"Everytime that I…"
"Pumbaa, not in front of the kids!"
The most obvious thing I can think of which fits in with the rhyming scheme and merits that reaction is that he says:
"Oh the shame,
Thought of changing my name;
And I got downhearted
Every time that I came…"
Sure, downhearted rhymes with farted but it’s written in a kind of Limerick style… What do you think?
Kids fart too! Why shouldn’t he say that in front of them? :S
Thank you for your input Mr Bateman (do I spy a psycho?), that’s very insightful. There does seem to be very poignant connection between the "predatory", calculated approach that Scar takes to adversity and Hitler’s totalitarian attitude… 
It was farted. he is a warthog after all and the visuals support the fart scenario
