After Stuart's brother Jordan commits suicide, one of the following scenes shows the funeral for Jordan. At the beginning of the movie after Nicole meets Stuart, she mentions in a call to her mother that Stuart is Jewish. So, if Jordan is Stuart's brother, then he must be Jewish too. Therefore, he would have a Jewish funeral. In a Jewish Funeral, the men wear yipot on their heads (small caps to symbolize that god is with them), and there is no wake afterwards, the body would be taken immediately to the cemetery (not to someone's house).
