I'd like to make a SANDWICH,
but I'm out of bread.
The Big Bang Theory Season 3, Episode 6

From now on, "frog" is me, "SANDWICH"
means you, and "lemon" means rocket.
The Big Bang Theory Season 6, Episode 3

Are you giving me half
of someone else's SANDWICH?
The Big Bang Theory Season 3, Episode 7

...is this subway, the transportation system,
or Subway, the SANDWICH shop?
The Big Bang Theory Season 1, Episode 17

Thank you for carving a smiley face
in my SANDWICH.
