The wall is covered by thousands of people's chewing gum in Seattle's Post Alley. Apparently the sticking of gum on wall started in the 90's while patrons waited in line for buying theater tickets. Numerous attempts were made to 'clean up' the alley by removing off the gum, but things didn't work out & above are the results. The gum spread into a Seattle tourist attraction.

Bubblegum wall at Maid Rite Sandwich Shop in Greenville:
The Maid Rite Sandwich Shop in Greenville, Ohio must have some tasty sandwiches, leading their customers (drive-up and dine-in alike) to loose their gum. How else can you explain the fact that customers routinely take chewed-up gum and stick it onto the outside of the building? The entire exterior of the shop is covered with wads of gum, both on the drive-up side and the side facing the street.
