joke - I thought you guys were listening to Justin Bieber.

Some funny mature jokes 

A)A girlfriend and boyfriend walked into the girlfriends house and the girlfriend said to her mom, "Mom, me and my boyfriend are going up to my room" and the mom says, "Ok honey, you kids have fun." 
When they are up their the mom hears: "Baby baby baby oh!" 
The mom walks to the door and ask, "What the hell is going on?" 
The girl says, "Mom were just having s*x." and the mom says, "Oh thank god I thought you guys were listening to Justin Bieber.


B)
A man gets home early from work and hears strange noises coming from the bedroom. 
He rushes upstairs to find his wife naked on the bed, sweating and panting. 
"What's up?" he says. 
"I'm having a heart attack," cries the woman. 
He rushes downstairs to grab the phone for ambulance, but just as he's dialing, his 4-year-old son comes up and says, "Daddy! Daddy! Uncle Fred is hiding in your closet and he's got no clothes on!"
The man slams the phone down and storms upstairs into the bedroom, past his screaming wife, and rips open the wardrobe door. Sure enough, there is his brother, totally naked, covering on the closet floor.
"You b*stard," the man says," my wife is having a heart attack and you're running around naked scaring the kids!"
