One "Big & Nasty" to go, please

Today I went to McDonald's for lunch, which is dangerous on several levels - one being that it is in a bad part of town (since I'm at work) and two being that (let's be honest) no one really knows what's in that freakin delicious artery clogging goodness that we call fast food. But the 83243 calories were all definitely worth it, as I got a great laugh! The person behind me told her friend she wanted a "Big and Nasty." I thought I must have heard her wrong, but her friends called her out and I realized it was not my mind that was in the gutter but hers. Nice! Make it a quickie to go, please.
