16. Melvin Costa's "I have a small penis" tattoo.
When: Since birth?
The MMA fighter's tattoo declaring the truth about his teeny weenie is the second most ridiculous tattoo on his body. He's a white suprmacist, so he also has the German Eagle symbol that was used by the nazis standing atop a swastika. In case his opponents weren't already trying to destroy him, they just found more motivation.
