Two peas in a pod

Here are two people that are one and the same.

Just a big and little version.

 They both take life very seriously,

yet they are super silly.

They make me laugh so hard sometimes!

 They are often misread.

This look you see here...

They aren't sad.

Or mad.

This, as Mark puts it, is their "neutral" face.

But neutral faces can often be misread as

mad or sad...

But they are fine.

They both love to do this:

 And play football, basketball, baseball

or badminton together.

Two peas in a pod.

 These are two of my favorite people...
