Cruz later brought up the prank when Kimmel asked the Texas senator who he liked least: Trump or President Barack Obama.
"Look, I dislike Obama’s policies more, but Donald is a unique individual," Cruz said.
"I will say, I was watching the early part of the show, and if I were in my car getting ready to reverse and saw Donald in the backup camera, I’m not confident which pedal I’d push," Cruz said, jokingly.
"There you go," Cruz said. "It is a powerful strategy and compared to Donald I am the quiet shy soft spoken one."
Cruz spoke with Kimmel about various personal topics, including his teenage dream of being a Hollywood actor, and his favorite cereal. FYI, it's Mueslix.
When Kimmel told Cruz that he didn't seem like someone who would have wanted to be an actor, Cruz joked, “I seem like a lawyer-politician? I just play one on TV.”
Cruz teased Kimmel about the host's salt and pepper beard after Kimmel noted that he is older than the 45-year-old Cruz.
"The salt and pepper beard, a distinguished look," Cruz told Kimmel.
Kimmel responded, "You’re not going to put me on the Muslim watch list are you?"
Cruz joked, "It’s already done, actually."
Cruz did drop the funny demeanor for a bit, and acknowledge his controversial statement to empower law enforcement to patrol Muslim neighborhoods. Kimmel pressed Cruz on the issue.
"We need law enforcement to work cooperatively with the community to prevent radicalization and to stop terror attacks before they occur," Cruz said.
When Kimmel said they'd have to agree to disagree on Cruz's stance, Cruz offered one more joke.
