*playing...*
5 minutes later:
Friend: it's like... pong... on a Wii... but not responsive... or fast... or -
you: but it's wall pong! With a laser!
Girlfriend walks into room, sees you both holding paddles and watching the laser bounce lazily across the board.
Girlfriend: ... I was going to ask if I could borrow your coat but now i think i am going to tell you that I am leaving you.
You: Aw, c'mon guys! It's wall pong!!
Girlfriend, to your friend: .... um... what are you doing tonight?
Friend: I was going to go to -
GF: wanna hang out? I guess i'm at my parents' place now, but we can go to a party...
You: Guys! this is so not fair! I NEED someone to play wall pong with!
