What could be funnier than Ellen DeGeneres' dry humor? Apparently, the TV host singing off-key on national television.

On this week's "The Ellen DeGeneres Show," actress/comedian Kristen Wiig was one of Ellen's guests. Ellen was saying that she thought she was the only one on earth who did not know the song "Let It Go" from the animated Disney movie "Frozen."

She then whipped out two microphones, and started a sing-along with Wiig. Both of them had earlier said that the only part of the lyrics to the popular song that they knew were the words "let it go," which they assumed would be in the song somewhere. Ellen said that they would probably go down in history as the worst cover of the song, E! Online reports.

The two sang it like they were in a karaoke bar. Initially, they were just sitting on their seats and later stood up as the notes got higher. They sang standing back-to-back and even climbed up onto the futon for comedic effect. They were so into it that they had a blast and so did that audience that night.

The duo sang the whole song while the audience could not control their laughter. They were also laughing the whole time while they were singing the song.

This was the first time that Wiig guested on Ellen's show. She later announced that her "Bridesmaids" comedy would not have a sequel. DeGeneres had said that Wiig should write again and that was when the actress revealed that she was working on a movie but not on another "Bridesmaids," adding it was better to leave it where it was.
