Practice makes perfect, right?

On Tuesday, "Breaking Bad" star Aaron Paul sat down with Jay Leno on "The Tonight Show" --where Jay uncovered one hilarious vintage clip of the Emmy nominated actor!

One of Aaron's first roles was playing a student in the high school production of "Romeo & Juliet" on "Beverly Hills, 90210" ... and lets just say he's come a long way since his West Beverly days.

Check out the hilarious clip above to see Paul's big acting debut, his first onscreen kiss and (most importantly) the 33-year-old's mortified reaction!

Aw, isn't Aaron so cute? Big thanks to Leno for digging up this gem featuring our beloved "Breaking Bad" star!

The actor has definitely improved his acting skills since the "90210" cameo.
