Heaven rooms

A man arrived at the gates of heaven.
St.Peter asked,"Religion?"
The man said,"Methodist."
St.Peter looked down his list and said,"Go to room 24,but very quiet when you pass room 8."
Another man arrived at the gates of heaven.
"Religion?"
"Catholic."
"Go to room 18,but very quiet when you pass room 8."
A third man arrived at the gates.
"Religion?"
"Jewish"
"Go to room 11,but be quiet when you pass room 8.
The man said,I can understand there being different rooms for different religion.But why I must be quiet when I pass room 8?"
St. Peter told him,"Well,the Baptists are in room 8,and they think they're the only ones here."
