In which Family Guy episode do Peter Chris Stewie and Brian throw up?

Answer 1

Brian doesn't wear pants... he's a dog.

Unless there's a special occasion like he's singing on stage w/ Frank Sinatra Jr., or he's working for the Quahog Police Department... but I digress, I'm guessing you're referring to the time he wet the floor in the grocery store in the episode "Brian in Love"

The episode is:
