Mayonnaise in a suitcase

Luc and Nivea asked me to pick up some things at a friend's place so I can bring it with me to Belgium.
No problem, I call this friend and ask about the CD's and such.
She then says also to take the "mayo".

???

I'm like - what?? Why would I need to take mayonnaise in my suitcase.
I ask her about it - "Did they actually ask about giving along the mayo?".
She said, "well - it's here..."

I don't know what to say...

So I said I wasn't very comfortable with that, it could break in my suitcase and then everything is full of mayo.
Well, she said, it's not very likely that "MAIL" is going to break...

CRACKING UP YET ??
