Dale Earnhardt Jr. turned everyone's stomachs on Tuesday afternoon by tweeting out a picture of the bizzare combination of bananas and mayo on a sandwich.

The Nascar driver, who is a longtime spokesman for mayonnaise brand Hellmann's, said he swears the unusual mashup is "delicious," despite loud skepticism from pretty much everyone else.

Logged on, saw a sandwich made with a banana and mayo.. Logging back off. — baeblades (@illexinati_) April 5, 2016

While it didn't get the most open-minded reception on the Internet, the practice of mixing unlikely ingredients with mayo is apparently a deep-rooted tradition in the South.

According to Garden & Gun magazine, peanut butter-and-mayo sandwiches have been a Southern favorite since the Great Depression.

The banana mayo sandwich combo reaction is always so passionate. What if you added peanut butter? That's always an option you know. — Dale Earnhardt Jr. (@DaleJr) April 5, 2016

It isn't the first time Earnhardt has mentioned this lunchtime oddity — he first tried to push the sandwich on Twitter users in 2014. But it took photographic proof that he wasn't kidding to really drive the point home.

Working with my friends @Hellmanns today got me thinking. Whats ur favorite use for mayo? Mine is a mayo/banana sandwich. #dontknockit — Dale Earnhardt Jr. (@DaleJr) March 14, 2014

Appalled Twitter users were evidently not ready to take Earnhardt's word for it.

I eat mayo. I eat peanut butter and banana sandwiches. I cannot think of mayo and banana without feeling very very sad — Hayes Brown (@HayesBrown) April 5, 2016

"Mayo and banana and sandwiches are a thing in the south"

For its part, Hellmann's appeared pleased with all the consternation and culinary discussion their brand spokesman had stirred up.
