Putting a hat on a hat 

An unnecessary addition to something that was previously working without it--like putting a hat on top of another hat. In comedy, this is used when placing two funny things too close to each other so that they distract from each other.

Bob told a joke on top of another joke. I warned him he was putting a hat on a hat.

Trying too hard to make something obvious, typically comedic.

1: Sigma
2: What's sigma?
3: Sigma balls! Get it? Because sigma kind of sounds like "suck my"!
4: Yeah dude I got it, you're kind of putting a hat on a hat here.
