The video above is the Ironman Triathlon of sing-a-longs, but viewers who weren't glued to Nick at Nite back in the day may not be familiar with the tunes. They are as follows (and with proper titles because we're professionals, dammit):
"Thank You for Being a Friend (Theme from The Golden Girls)"
"Movin' on Up (Theme from The Jeffersons)"
"Theme from Diff'rent Strokes"
"Theme from Good Times"
"The Fishin' Hole (Theme from The Andy Griffith Show)"
"Theme from I Dream of Jeannie"
"Everywhere You Look (Theme from Full House)"
"Believe It Or Not (Theme from The Greatest American Hero)"
"Theme from Martin"
"Theme from Three's Company"
The compilation ends with a classic -- you can probably guess which one.
