I think the lollipop song was actually a real song.

Kars for Kids I am sure its a good charity but song just melds into the brain and you replay it in your mind for hours. I think this was the song spoofed on Will and Grace by Karen and Jack. 

It’s A Rainbow good god song is annoying. First time I heard this I thought my ears aren’t bleeding. Wow.

Lollipop I saw it four times last night watching Manifest on OnDemand. Manifest is excellent. Still not sure what the ad is for.
