Kurt Busch surprises birthday winner Kyle Busch with mariachi

When Kyle Busch pulled into Victory Lane at Kansas Speedway after his Buschy McBusch Race 400 win on Sunday afternoon, little did he know the party had yet to begin.

Not only did the No. 18 Joe Gibbs Racing Toyota driver notch his first victory of the season — and first with new crew chief Ben Beshore — he did so on his 36th birthday, in a race that couldn’t logically wind up with neither he nor his elder brother, Kurt, in Victory Lane. All this to say: there were plenty of reasons for the Busch brothers to turn up the party dial … so they did.

Arriving at the airport much earlier than his brother after notching a 15th-place finish, Kurt was able to have a full fiesta in place for the southwestern-born brothers to kick off Cinco de Mayo a few days early for a little impromptu birthday/victory party.

It took some time for Rowdy to show up, but it was worth the wait.

Even Samantha and Brexton Busch were able to join in on the festivities.
