As Bob welcomes the viewers, Sesame Street is suddenly beset with an outburst of jackhammers and roaring compressors. Maria and Tom come by and see that workmen are fixing the street, and they complain about the noise. Oscar pops up wearing a hard hat and says he's heading to where they're digging, not wanting to miss all the noise, dirt and mess.

Today, Rafael and Luis open up their new Fix-It Shop, and Big Bird wants to give them a gift. So he puts on various disguises and acquires all the free flashlights they are giving the customers, just so he can give them back as a gift.

Big Bird is bored because he has nothing to do. He asks everyone he meets - Maria, David and Bob - if he can help them to do something, and they all decline his offer. Muppets-Sherlock Hemlock investigates the letter N.

Tom observes that there are some things that it's better to do inside and some things it's better to do outside.
