In 1967, the Topps baseball card company introduced a new line of comic trading cards which parodied existing products and iconic advertisements. Topps called this series Wacky Packages, although many avid collectors still refer to them as wacky packs. Wacky Packages were sold alongside baseball cards and other novelties in the candy section of many grocery and department stores. Wacky Packages could also be found in specialty card trading shops and some drugstores.

Much like their baseball card counterparts, Wacky Packages contained a random mix of collectible cards and a stick of bubblegum. Unlike baseball cards, original Wacky Packages cards were punch-out stickers. Later editions of Wacky Packages could also include solid cut-out cards, featuring sections of a larger puzzle on the back.

Wacky Packages parodied most of the consumer products of their time. Crest toothpaste, for example, could be rendered as Crust Toothpaste on Wacky Packages cards. The artwork, created by a mix of Madison Avenue and underground artists, would satirize every detail of the original Crest packaging, from the iconic block lettering to the seal of approval. Grotesque figures and gross-out humor were hallmarks of Wacky Packages parodies.

Other consumer products were also popular targets for Wacky Packages producers. Band-Aid bandages became Band-Ache, Skittles candies became Spittles, and Liquid Plumber drain opener morphed into Liquid Bummr. All of the artwork and advertising copy was based on these skewed concepts.

In the case of Liquid Bummr, the main image features a depressed man being ejected from a sewer drain. The advertising copy reads 'It Spews Bad News' and 'Liquid Bummr: For All Depressed Types'. In a Wacky Packages spoof, few details go unnoticed.

The Topps company continued to produce Wacky Packages on a semi-regular basis until 1992. At different points during the original production run, Wacky Packages outsold Topps' baseball card lines. Interest in Wacky Packages may have waned for the younger demographic, but nostalgic adult collectors have continued to keep the Wacky Packages card trading industry alive. Certain original Wacky Pages cards and promotional items are extremely rare and valuable, especially uncut panels and cloth stickers issued in 1968.

In 2004, the Topps company decided to reissue classic Wacky Packages and commission new titles as well. These new Wacky Packages are now sold as foil-sealed collectible packs containing a mixture of paper stickers, solid cut-outs and special foil stickers. The tradition of including puzzle pieces on the back of each card has also been preserved. New Wacky Packages targets include familiar websites, movies, television shows and video game titles.
