Excuse me sir, there must be a lamp youve confused me for

I just found out about this meme today-

I could tell it was a meme on my YouTube suggested. Excuse me, LEGEND (with Ralsie, Kris, and Susie doing this face thing). A bit of digging happened to find where the meme originated. It's a decent song, I must say, but the face is just so silly to me.

Ok, now they're really about to sing What's Going On

Charlies inferno is pretty good

It looks like Frisk is about to sing What's Up

can someone please explain the original meme for this to me? because me no understand

It’s a song i think

Originated from when the boys blew up because of the new episodes, and a trend was making edits of a comic panel of a character named butcher in that pose with the song "Charlie's Inferno", which has the lyrics "excuse me sir" and it eventually became a meme
