Why is there background laughter in The Big Bang Theory 12x15 @11.30?

Question

The scene I'm, talking about is when Sheldon wakes up and makes himself a cereal breakfast.

There's literally nothing that gives away Leonard sleeping on his couch and nothing else comical that would be a reason to that laughter?

I've read an article about TBBT creation, and they mentioned that on TBBT each comic scene gets tested on the audience and goes unedited into production only if the audience laughs.

There's nothing comical up to the moment camera goes off to the coach revealing Leonard, so why on Earth did they edit background laughter there?

_{I do realize that jokes on TBBT have gotten way downhill over time, but it's clearly way different.}

Answer 1

I've rewatched the episode and the audience laughs when:

• Sheldon yawns
• Sheldon looks forward with a weird expression
• Sheldon is mixing the cereal with the milk and walking

In my opinion, the audience laughs because:

• Sheldon faces and expressions
• Sheldon is kind of sleepy and grumpy
• The fact that Sheldon has some kind of morning routine
• The scene is too quiet and they added the laughs.
• I also think some of the laughs are from people seeing Leonard on the couch before us viewers.

I also chuckled a little bit during the scene before I knew Leonard was in the couch, Sheldon is just humorous...
