Ole was going down on Lena eventhough she was having her period.  Sven had decided to drop by and rang the doorbell.  Ole went to see who was at the door.

When he opened the door a shocked Sven exclaimed, "My God!  Ole, what is that all over your mouth?"

Realizing he forgot to clean his mouth before answering the door, an embarrassed Ole thought before answering, "Ah... Umm... I.. I was just eating a jelly sandwich."

A puzzled Sven replied, "Well by the looks of your chin are you sure it wasn't a peanutbutter and jelly sandwich?"
