I Have A Time Machine & It's Called BED

"I have a time machine and it's called bed. When I sleep there, I wake up in the future. So... any girl wanna travel with me?"

I got this SMS from a kid--who will not be named for the protection of his identity because he's a regular of our kids' Sunday school/cell group at church--that I found funny and disturbing at the same time that that kind of message came from him, even if it's intended to be a joke. What more disturbs me is the fact that he's a church kid! I can just wonder if he actually knows what the message means.
