Despite playing hilarious characters who often ask incredibly awkward questions [1], Zach Galifianakis [2] admits he was downright stumped when his 2-year-old son, Rufus, asked him a unique question involving anatomy [3]. While promoting his new Netflix movie, Between Two Ferns, on Jimmy Kimmel Live, the 49-year-old actor told a story about what happened when Rufus accidentally saw his dad's penis while he was peeing [4].

"My son — who's 2 — saw me when I was peeing, and I was done, and he walks up to me, and just the way he said it, he goes, 'Dad, can I touch your big penis?'" Zach told Jimmy. Naturally, Zach told Rufus no, and laughed it off — but seriously — what a doozie! Tune in around the 5:40-mark to get the full exchange, as well as a damn good laugh.
