The Hudson Valley is freaking out over the thought of substituting mayo for cream in their cup of joe. But just how bad can it really be?

Newsman Bobby Welber reported on a story about a Philadelphia sports broadcaster named Jim Salisbury who tweeted that he once ran out of cream and reached for a jar of Hellman's instead. The Internet let out a collective gasp at the thought of this unholy concoction, flooding Twitter with messages of disapproval.

We wondered if mayo in coffee would really taste as terrible as it sounded, so we decided to conduct another one of our famous Boris and Robyn Show taste tests.

That's right, we tried mayonnaise in our coffee just so you don't have to.  You're welcome.

We want to know if you've ever substituted anything else for milk in your coffee. Ice cream? Whipped cream? Mashed potatoes?  Let us know your crazy coffee concoctions in the comments section below or on our Facebook page.
