It's National High Five Day! Let's relive some of these classic hand slap moments in movies and tv.

These are some of my favorite high fives. Which is kind of a weird thing to have a 'favorite' of. But once you see them, you'll know they're kind of iconic.

1. Jackass 3D

2. Scrubs, The Todd

3. Top Gun

4. How I Met Your Mother, Barney

5. The Fresh Prince of BelAir (Yeah, I know it's technically a handshake. But it's an open palm slap with two hands above the waist...THAT CONSTITUTES AS A HIGH FIVE IN MY BOOK.)

BONUS: This guy in New York who started high fiving people who just wanted to hail a taxi.
