Of course, if you want silly rather than touching, there's "Old Blevins" by the Austin Lounge Lizards: guy has a fight with his woman, goes into a bar, and is earnestly confronted by Old Blevins, who has some words of wisdom for him:

And he said "Bla bla bla bla bla bla bla bla bla In San Francisco
"Bla bla bla In 1963
"Bla bla bla bla bla bla bla bla bla I don't remember"
And that is what Old Blevins said to me.

After several verses of this (with some silly insertion lines including "Bla bla bla Had no effect on me" and "Bla bla bla bla bla Mistakes were made"), the younger guy has indeed found the wisdom he was seeking, and goes back to make up with his woman so that he doesn't end up a lonely old fool in a bar muttering "Bla bla" to strangers.
