During a pre-race grid walk ahead of the Miami Grand Prix, Jimmy Fallon snatched a branded mic sock from Sky Sports F1 pundit Martin Brundle, bit it, and returned it. Brundle quickly reclaimed the microphone on air and admonished Fallon, “Don’t do that again.”

Brundle later shared video of the moment on X, posting, “In 30 years of broadcasting I’d never wondered what a branded microphone sock tastes like.” The clip went viral and was widely framed as a lighthearted, unexpected celebrity moment rather than a serious safety or professional complaint.

Fallon was attending the Miami Grand Prix as a guest of Red Bull and Racing Bulls. The grid walk included other celebrity interactions, including a separate exchange between Brundle and DJ Khaled during the Racing Bulls livery reveal.
