David Rush of Boise, Idaho has another Guinness World Record to add to his resumé. Rush - who owns more than 200 Guinness records - just attempted new record by fist-bumping 152 people in 1 minute.
He said it was a fairly easy record to break, describing it as "more of a logistical challenge than a physical one".
The video has been submitted to Guinness for review. Rush's record-breaking feats have gotten him on the Today show and America's Got Talent.
Last year Rush made headlines by breaking 52 records in 52 weeks, and he hopes to break his 250th total record later this year - all to promote STEM education.
