Today's post is brought to you by the number 5.

We've all grown up with Sesame Street, right? We all know who Kermit, Bert, Ernie, Big Bird, Cookie Monster, and Grover are, but what about those Muppets who, while not as popular, are still a vital part of the human/Muppet mix who populate the popular street? Or are no longer a part of Sesame Street at all? There's way more than five, I can tell you that, but here's five of my favorite "second tier" Muppets from Sesame Street. Some are gone, some are just forgotten. Grab a bowl of Cheerios and your footy jammies and share some of your own memories in the comments. Now let's do it:

Prairie Dawn - Prairie Dawn was a precocious little girl with blond hair who would try to put on plays with the other Muppets. Usually the play would get ruined and the set would be destroyed. Prairie always tried to keep her composure, but eventually she'd blow her top. She wasn't much of a character, but she was a great straight man to play against the likes of Ernie or Cookie Monster.

Herry Monster - Yes, it's spelled "Herry." This gentle blue Muppet is super strong, but he has a heart of gold. He doesn't have Grover's anxiety or Cookie Monster's insatiable appetite for cookies. Really, Herry doesn't have shtick to call his own. He's just a kind, gentle creature, and for any preschool kid sitting in front of the television, that's all that's asked.

Don Music - This character hasn't been on Sesame Street for many years, but some of you may remember him as the frustrated pianist who would bang his head on the piano when he couldn't get a song right. Apparently kids started imitating his head bashing at home, so the character was given the boot.

Roosevelt Franklin - My memory of Roosevelt Franklin is an album my grandfather had when we were kids called Roosevelt Franklin Sings. He was a small purple "human" Muppet whose voice was provided by Matt Robinson, the first "Gordon" on Sesame Street. Roosevelt actually became quite popular in his short time on the show with his love of rhymes and poetry, but some felt the character represented a negative cultural stereotype, so he too is no longer with us.

Sam the Super-Automated Robot - I had to dig deep into the recesses of my mind to recall this character, who I don't think ever really took off. I have only vague memories of Sam, but I remember he would clank and rattle and pretty much screw up any task that was given to him. Apparently he didn't leave too much of a lasting effect on anyone else, either, because I think he was gone as soon as he arrived.
