I have seen this a few times recently on t-shirts, but my sense is that it is not strictly a t-shirt thing. And those t-shirts were being worn by people on-stage at the close of Saturday Night Live, but my sense is that it is not strictly an SNL thing.
When Seth Meyers hosted SNL earlier this season, he came out at the end wearing a t-shirt that read…
Axel&
Ashe&
Alexi&
Frisbee
It was a shout-out to his family; these are the names of his kids, wife, and dog. (Frisbee is the dog.)
Also this season, someone on stage (I forget who) was wearing a similar t-shirt with the names of former SNL cast members. It was something like…
Farley&
Spade&
Sandler&
Rock
The latter example is an approximation as I’m going by memory. I’m pretty sure I got the earlier example right, though, because I found it for sale. Cool; who doesn’t want a t-shirt with the names of Seth Meyers’ family on it? If you don’t mind clicking on a site with a Liechtensteiner domain name, you can see it here: https://rsz.tzy.li/816/918/tzy/previews/images/001/442/499/601/original/axel-ashe-alexi-frisbee-shirt.jpg?1539529371
I am assuming both t-shirts were created in the style of something that already existed. Does anyone know what original design these are playing off of?
