Drew Lynch‘s self-confidence is peaking as he performed Tuesday night live on NBC for the semifinals of America’s Got Talent, not only laughing at his own jokes and the warm reception the Radio City Music Hall audiences have given him, but also dropping the mic and turning his back to them at the end of this three-minute set. Lynch joked about how his stutter made a customer-service rep think he was a woman with bad reception on a phone call.

Tune in Wednesday night to see if Lynch advances to the finals of AGT Season 10.
