Many food products come in resealable packaging.  The joke is when someone eats the entire package and the resealable feature is not necessary.

Probably seemed like a good idea at the time, but who thought it would be necessary to make a bag of M&M’s resealable?

Dear Caramilk,
While I appreciate you offering resealable bar wrappers, that won’t be necessary.
Thank you,

You know those large M&M candies bags that are resealable? Mine never last so long as to be needing a resealable bag.
