The TV show Joanie Loves Chachi (1982-1983) was a Happy Days spin-off that focused on the characters Joanie Cunningham (sister of Richie) and Charles “Chachi” Arcola (cousin of Fonzie).
Joanie Loves Chachi didn’t last long, but it did make an impact on expectant parents.
- 1983: unlisted
- 1982: 9 baby boys named Chachi [debut]
- 1981: unlisted
And the baby name Joanie was boosted back into the top 1,000:
- 1983: Joanie ranked 1,080th
- 1982: Joanie ranked 879th
- 1981: Joanie ranked 1,074th
Later that year, though, ABC’s Joanie Loves Chachi got destroyed (ratings-wise) by NBC’s The A-Team. Chachi never appeared on the charts again, and Joanie went downhill until it fell off the SSA’s list entirely (i.e. was given to fewer than five baby girls) in 2008.
P.S. Here’s the cheesy Joanie Loves Chachi opening theme song. Don’t say I didn’t warn you…
Update (2/26/15) – Just spotted Chachi-variant Shashi, which was a one-hit the same year.
