Will Ferrell who is an American treasure, continue his insane stretch of appearances on ‘CONAN’ when he showed up this week with tiger face paint claiming he came from a kid’s birthday party, he also insisting on a singing the 70’s pop hit ‘Superstar’ by the Carpenters which he claimed the young birthday boy wanted to hear. Ferrell than continued to bulldoze host Conan O’Brien by insisting that he has “sing the entire song” or he would restart if interrupted. Ferrell also revealed the birthday boy is his son but previously was not aware who is father is.

So you think it ends there right? Nope. The star of ‘Anchorman’ and ‘Stepbrothers’ continued to sing the song through the commercial break, and into the show’s end credits.

Ferrell is starring the upcoming comedy film ‘The House’ in theaters on June 30th.
