Squirrels have it good

Gabriel, Drake, and Lisa go for a walk and Gabriel points out a squirrel in a tree. 

Lisa announces that she wishes she was a squirrel. When Drake questions this, she tells him that her reason for wanting to be a squirrel is that squirrels don't have to wear pants. 

Drake is disturbed. He's supposed to be shaking Gabriel's shoulder a little like "DID YOU HEAR WHAT SHE SAID? WHAT THE FUCK, RIGHT?". 

Apparently, Lisa thinks that pants are for the weak. Gabriel thinks it's awesome. 

I can't explain this. It kinda just happened.
