I called Christina (I call her Xena) to see if she could bring something to our picnic...

Me: Hey, so I was calling because we (Pam and I) were wondering if you could bring a sheet or a blanket.
Xena: ...Well...I could bring a pie.
Me: Because...a pie is equivalent to a sheet or blanket...?
Xena: Oh! I thought you were talking about what food we were going to bring!
