i found this on this blog and, so, ignoring the fact that "underneath is misspelled," this really doesn't make much sense.
however, the blog author provides the following Theory:
"Okay so this is how I imagine this conversation went:
Walmart Employee: “Hello 'dis Walmarts, how can I help you?”
Customer: “Yes, I would like to order a cake for a going away party this week.”
Walmart Employee: “Whatchu want on the cake?”
Customer: “Best Wishes Suzanne.” And underneath that “We will miss you”.
in addition to the fact that i just had diet coke and a chocolate mint candy cane for breakfast, I CANNOT STOP LAUGHING about this.
