Snoop Dogg's Umbrella

This joke is funny because Snoop Dogg says "Fo' shizzle" a lot. Drizzle is like a little rain. So instead of saying "For sure" he says "Fo' drizzle" because rain is also drizzle and it sounds like "Fo shizzle". You probably think that is really funny, but you need to watch Rick and Morty to understand humor.
