Well i was at charlies, and I used Marks phone to phone home for a sec. and i put it in my pocket on habit and forgot about it.
When we where going to Donna's mini mart I realized i had it, so i suggested "hey, lets make some prank calls."
Mark was all for it, and once we got to Donnas we went behind it and in the dark, he couldn't tell it was his. (you'd think he would.. right...)
So we where calling people, we tried Megan(A person we sespect another friend likes, but refuse's to admit it). And at one point Mark was all "lets phone a sex hotline."
That was the cream on the cake as he was talking to this miss there and i peeked in with a comment that nailed it "Mark..thats your phone."

his face was priceless... its like.. Cena getting hit with a Punch...but with more shock.

turned out to be his mother phone... epic
