When one gets asked to watch a friend’s house, it’s sort of an unwritten rule not to make any major changes to the house.

Ohio State graduate and fan Ty Higgins didn’t make any drastic changes to his buddy’s house, but he did leave his mark. As Higgins explained in a Facebook post, his out-of-town friend is a Michigan fan.

So when Higgins mowed the lawn, he left a little script O-H-I-O for him in his backyard lawn (it’s better with the audio).

Ah, of course.

Who knows how Higgins’ friend will react to his newly-manicured lawn, which he’s probably seen all over the internet.

Perhaps Higgins’ backyard will have a big block “M” mowed into it in the near future.
