Identification at the Bank

Izzard went into a Baltimore bank to cash his check. Since he didn't have an account there, the teller asked if he could identify himself.

"Sure," said Izzard.
"There a mirror around here?"

"There's one on the wall right beside you," said the clerk.

Izzard took a glance in the mirror and heaved a sigh of relief.

"Yep!" he said. "It's me, all right!"
