Chips and Dip

I never eat potato chips,
Especially with dip
But sometimes, when there’s company,
Resolve just seems to slip.

And once I start, I prove the point
That ad campaign’d begun –
When chips and dip are waiting,
You can never eat just one.

So here I go, with no control,
Each chip leads to the next
And when my pants won’t zipper,
Well, I shouldn’t be perplexed.
