Community vs How I Met Your Mother

My favorite television show is hands down Community.  I don't even have to think twice.  However there is another really cool show called How I Met Your Mother.  Recently I began re-watching the How I Met Your Mother series and there are some interesting ties between the two shows.  It doesn't really mean a lot, but I do enjoy finding these connections.

#1  The 88.

The 88 is a four piece rock band.  They also perform the title song for Community.  It is a great song and the only song of theirs that I own.  How does this band tie in with How I Met Your Mother?  It is the same band that Lily and Marshall hope to get for their marriage.  They are feature in the prom episode where the group breaks into a high school prom in an attempt to find out if The 88 could play their wedding song.
