Tip of the Tongue, Teeth and the Lips 

1)A vocal warm up tongue twister
2)A line uttered by Jack Black in School of Rock.

1)The lips, the teeth, the tip of the tongue,
the tip of the tongue, the teeth, the lips.

2)"Tip of the tongue, teeth and the lips.
OK.
It starts off...
...a dark stage,
and then a beam of light,
and you can see me and my guitar."

On the tip of my tongue 

knowing something that cannot immediately be recalled, like a well-known word or familiar name. When experiencing it, people feel that the blocked word is on the verge of being recovered. Despite failure in finding the word, people have the feeling that the blocked word is figuratively "on the tip of the tongue."

I can't remember the word for eating pussy, but it's right on the tip of my tongue.
I can't remember the word for licking balls, but it's right on the tip of my tongue.
I can't remember the slang word for "anus," but it's at the tip of my tongue.

tasting urine on the tip of one's tongue 

The condition in which one needs to urinate so badly that any further delay will cause bladder rupture.

I think tasting urine on the tip of one's tongue is a sure sign one is in trouble.

I held it for as long as I could, but when I tasted urine on the tip of my tongue, then I knew I was in trouble. I had to pull over and go in the ditch.
