Synopsis
The episode starts as SpongeBob and Patrick walking to each other and then they start to play - the idea of their game is to holler at the vehicles that pass by, which angers Squidward and some of the people in the vehicles. Then Patrick falls  asleep and when he wakes up he has a beard. Then Squidward passes by and offers to teach Patrick everything he knows about how to be mature which upsets SpongeBob. SpongeBob decides to follow them promising he will learn how to be mature as well.

The three go into Squidward's house for a grown-up makeover. SpongeBob shows off his new look. Patrick likes his look until Squidward reminds him that he really shouldn't.

They then go to a restaurant, and Patrick and Squidward order some fettuccine while SpongeBob orders the milk and cookies.

Then they go to the art place and SpongeBob follows them around and Patrick and Squidward tell the security to kick him out and he first put him out softly, but he doesn't leave so he ends up kicking him. SpongeBob sees Squidward and Patrick walking and Squidward mentions that the beard was the best thing that ever happened to Patrick other than himself. SpongeBob tries to remove his beard to restore his friendship. Squidward stops him and says that they are through with him.

Then Squidward and Patrick go to the Opera house and they see a lady which is really SpongeBob singing opera which Patrick says "she's beautiful".

After SpongeBob sang opera to win Patrick back, Patrick begins to cry and sees the beard is really a sea urchin and the sea urchin woke up and ran away from Patrick. He chased it until SpongeBob says Patrick's name and he says "How do you know my name?" and he says that he is SpongeBob and they make up again then Squidward told all the guests that the show is horrible, but they disagree and threw food at him then the episode ends.
