My brother-in-law has several tattoos. Unfortunately, the artist was a beginner and basically used him as "practise". My brother-in-law went through with it because of the cheap price (yes, he did pay something). So the tattoos, while they are supposed to look tough and scary (skulls and the like), they actually look sort of lame and cartoony. Now my bro-n-law is stuck with these tats for the rest of his life. Oh well.
As an aside to my little antecdote, a Muppets tattoo would be pretty cool, but I couldn't afford it.
