A SHOPPER was left in stitches after discovering his chocolate Santa had a willy.  Jason Greaves, from Blackley, Lancashire, picked up the £1 treat from his local Tesco last week when he was feeling in the Christmas spirit  The 28-year-old unwrapped the St Nick-shaped chocolate when he got home and noticed something strange  On inspection he found the confectionery Father Christmas had a festive phallus  He called over partner Candice, 19, and the pair giggled before taking a few pictures  The clothing company director left the Santa uneaten while he contacted Tesco to alert them of a possible bad batch  Jason, from Blackley, Lancashire, said: “I only picked it up because it was by the till and I wanted something sweet  “I took it home and was going to share it with my girlfriend.  “When I saw it I had to look again I just broke down laughing to be honest.  “I don’t know if it was a warehouse worker’s last day and they were having a laugh or whether it was just a complete accident  “But for it to be in the exact place where you’d expect it to be – it just seems more than a coincidence  “It’s a funny thing to happen. Of course if I was a kid this would be a different story  “I did tell Tesco this but they didn’t seem to care.”  A spokesman for Tesco said: “Oops…It looks as if Father Christmas has revealed a little too much on this occasion  “Of course if the customer wants to return the product then we can arrange this at their nearest large Tesco store ”
