A Swedish Lego lover has put his 300 kilo prize collection of building blocks up for sale for 75,000 kronor (11,500 U.S. dollars) to mend the relationship with his wife, local media reported on Sunday.

The online daily Local reported that, the man's advertisement, posted on the popular Swedish buy-sell website Blocket, quickly went viral after the man marked it as "300kg Lego - save my marriage."

Last Friday, when his wife yelled at him now get this shit out!" he seemed to start treating the matter seriously. "I don't know if it was me or the Lego she was talking about but I think it was the Lego," the man said online.

Due to the sheer amount of his collections, potential enthusiastic buyers will likely need some transportation to close the deal. The lot, as reported, is boxed in dozens of containers, and weighs in at a hefty 300 kilos plus another 20 kilos for instructions.

Among the collections are several items from the Lego Technic range, designed for more advanced builders, including the remote controlled excavator Volvo. There's also approximately 44 kilos of wheels and tyres and a practically complete collection of the Lego space range.
