When something is so obvious that you can't imagine why it was not originally invented that way. For example, when the suitcase was invented, why did it not originally have wheels, so obvious!

The best Jewish summer program you will ever attend. Whether it's traveling cross country, Israel, east, west, or cruising to Alaska. USY on wheels will create memories and friendships that last a lifetime. Singing Ruach, Shabbat shopping, and night time bonding activities are just a few of the amazing experiences USY on wheels has to offer.

That guy you invite to the amusement park that no one really likes that much, but you invite him anyways cause otherwise your five-person party would always require one person to sit awkwardly alone.

In a group of 6 friends, the only person who is not in a relationship. (The 5 friends and their partners + 11th wheel = 11) This character may be known as lone wolf, the bachelor, the free man. Most likely the coolest of the group, too cool for the opposite sex. The 11th wheel does not in anyway care that he/she is the 11th wheel. He/she's cool with it. Really fine with this.
