some context for people who aren't Mariners fans:
Cal Raleigh's nickname is "Big Dumper" because, like Al Pacino said in Heat, he's got a great ass
he's hit 60 home runs this season
a Mariners fan shows up (to a game in Detroit, not even a home game) wearing a "Dump 61 Here" shirt
Cal Raleigh hits his 61st home run...and after bouncing in the bullpen it basically lands in this dude's glove
and then he takes off the shirt...to reveal HE'S BEEN WEARING A "DUMP 62 HERE" SHIRT UNDERNEATH IT THE WHOLE TIME
