Frosty the donkey
An unassuming animal sanctuary in Devon, England, is home to one exceptional donkey for whom no entryway is off limits, according to this charming video, provided by the Donkey Sanctuary. Frosty the donkey has learned to turn doorknobs with his mouth (just check out the video!), a skill which he apparently finds most useful in opening up the food shed.
Though Frosty hasn't shown any inclination to use his dextrous skills for escaping from the sanctuary, he nevertheless typically gets first lick at dinner. Perhaps to Frosty, freedom simply means having a full stomach.
