Twins

My girlfriend said "I'm seeing someone behind your back"
I said "I know, that's my conjoined twin, Michael"

Loving Confession

Brittany was on her deathbed, with her husband Adam at her side. She kept trying to tell him something, but he kept saying, "Shhhh, don't worry now darling, just rest." "But honey," she whispered, "I need to make a confession before I die... I slept with your brother, your best friend, and your father." "Don't worry about it, sweetie," replied Adam as he wiped the tears from Brittany's cheek, "I know. Why do you think I poisoned you?"

Sex with Sister

My girlfriend's sister invited me to have sex with her while we were waiting for my girlfriend to get home. I didn't say anything and started to walk to my car. As I opened the door, my girlfriend came out from the kitchen and hugged me with tears in her eyes as she told me that it was a test of loyalty and I had passed!
Moral of the story: keep your condoms in your car.
