The Song:

You can't make friends with salad.
You can't make friends with salad.
You can't make friends with salad.
x10 or some larger number.

The Backstory:

Robinwood. You're sick of that word.
Our group leader was just sitting around, we were waiting for him to say something, and he just randomly singing 'You can't make friends with salad' and when he stopped, a girl was like, "Why are you singing that?" And he just gave her a weird look and...
"You can't make friends with salad."

You needed to see us sitting bored, and him just randomly come out with, "You can't make friends with salad..." To find it funny...

P.S On the last day, we were sitting around the dinner table and there was silence.
So, our group sings...
"You can't make friends with salad!"
And you wouldn't believe the weird looks we got. xD

Lol, I have that stuck in my head right now...;o
