Tinker is one of the most successful bell ringers for the Salvation Army's Red Kettle Campaign.  And he lives in West Bend, WI.  He now brings in about ten times the normal average.  He uses his mouth to ring the bell and then holds up a sign that reads "Thank You and Merry Christmas."  He'll even let you pet him :)

Hmmm... I wonder if he's related to Dominic the Donkey???

Check out a video of Tinker from a few years back...
