Patch, a Jack Russell terrier went missing from his home in County Kildare in Ireland. For a reason known only to him, he jumped on a train to Dublin.
The officials at Irish Rail found him and tweeted a picture of him. After being re-tweeted hundreds of times, it took just thirty minutes before his owner saw him on her own twitter feed.
They were reunited shortly afterwards.
