David Bote's walk-off grand slam earned him a meet-and-greet with Bill Murray

The Cubs staged an absolutely thrilling comeback on Sunday night at Wrigley Field, erasing a 3-0 deficit to stun Ryan Madson and the Nats with a 4-3 win -- and it was all thanks to rookie David Bote, who clubbed a 2-2 grand slam to center field to send the gathered masses into a frenzy.
Also at the Friendly Confines for the night was Bill Murray, noted Cubs superfan who's become about as visible at Wrigley as the ivy itself. 
He had a sweet vantage point of Bote's slam, which looked pretty epic in slo-mo (check the bottom-right corner of this GIF):

And he definitely enjoyed that view of the rookie's heroics: 

This was the 29th ultimate grand slam in MLB history, as it's not something that you see very often. 
Bote has a flair for the dramatic, as just a couple weeks back he tied a game against the D-backs with a two-run, ninth-inning homer off Brad Boxberger:

The pair shared smiles afterward:

The kid definitely knows how to get on Bill Murray's good side.
