The Inventory
From Homestar Runner Wiki
The Inventory is a secret club where video game characters relax and play games when they aren't working. Strong Bad and Pom Pom have played Texas Hold'Em poker here. The building appears to be a warehouse with a metal door and a lit sign displaying the words "The Inventory". This metal door isn't used, as a hidden elevator in the floor goes down into the real club below. The club is shown to have secret rooms, as a bookcase is opened and closed to allow passage to an unknown area. The club was founded in 1919, in response to an early draft of the prohibition ammendment, which would also have outlawed games. The club has remained secret ever since, just in case a similar law is ever created in the future.
