Twitter has become the new domain for stupid acts and promises and this weekend's football fixtures haven't failed to deliver.
Last week saw a Man Cover Himself With Jam after Nicolas Bendtner scored the winner for Arsenal against Cardiff.
For Chelsea fan Lee Mitchell his promise resulted in a more permanent outcome after he tweeted if John Obi Mikel scored against Derby, he would get his name or Chelsea badge tattooed on his rear end.
If Mikel scores today I'll get his name or the Chelsea badge tattooed on my ass

Well as luck would have it Mikel scored the opener, and doomed the fan to having his name on his ass for life.
There's no way he'll regret this one in years to come.
