Pack Busting and Flipping with Jimmy Fallon and Bob Costas

Save big on authentic collectibles and memorabilia in the Semi-Annual Clearance Sale

Jimmy Fallon and Bob Costas talked baseball and other topics for awhile on a recent episode of Late Night on NBC.

The real fun came afterward.

Fallon trotted out some 1989 Topps baseball packs (maybe the best publicity ’89 Topps has gotten since…oh…1989) for the two to open.

After a good-natured ribbing of poor Jim Walewander, they commenced to having some serious fun.
