Coffee of Doom

The place of employment and much scenery for the majority of the characters of Jeph Jacques' web-comic Questionable Content, where sarcasm and good coffee--not frappuccinos--reign. According to the Local Alternative Rag, "The hip/not-hip place to fulfill your caffeine jones."

Mario's Tunnel Of Doom 

A very unusual cave created by a mysterious floating head, no records have been written about this cave nor has anyone escaped it for those who have entered it. However, some believe that the cave was emerged in March 8, 1991. Its location is unknown but some say that the only way to find the cave is by entering the Bermuda triangle. No one really knows what is in the cave or where it really came from...

I wouldn't go in Mario's Tunnel Of Doom if I were you...
