On Tuesday, Baylor named Matt Rhule as its next head coach. Rhule spent the last three seasons at Temple, where he compiled a a 28-23 record.

Some Temple fans decided to take to Twitter to voice their frustrations about losing Rhule to Baylor, and decided to tweet at the head coach himself. There was just one problem: They used the wrong Matt Rhule’s Twitter handle. Instead of the head coach, they got high school student Matt Rhule.

We’ve seen mishaps with Twitter handles happen before. During the 2016 NFL draft, the NFL’s Twitter account accidentally tweeted at the wrong Connor Cook, after the quarterback was taken by the Oakland Raiders. Instead of the signal caller, they tweeted at a firefighter paramedic who was also named Connor Cook.

And then there was the guy who shared the same name as NFL head coach Chip Kelly who started getting tweets sent his way on the day the Philadelphia Eagles fired Kelly the coach. The 41-year-old executive for a California start-up with the handle @chipkelly got some pretty nasty things said to him, according to Philly.com.

Can I have the last 3 years of my life back, @chipkelly?" one asked. Another user sent him a 10-tweet screed with racial undertones that challenged Kelly's coaching philosophy. One tweeter sent a photo, asking him to look "into the innocent eyes of this Eagles fan and say sorry." And then: "@chipkelly even if you're not the real Chip Kelly he needs an apology from someone.

Always double check your Twitter handles, salty fans.
