Lost foot print.

Bob stopped by Grrr's cave for a coffee and to hang out.
"What time do you think the Girls will be back Bob?" Grrr asked.
"Well, Stef was telling me about a new shoe store 'that has some nice things'".
"Guess we won't see them till after lunch". Said Grrr.
"Nope". Said Bob....
"Nope". Said Grrr.
"Funny thing". Said Bob.
"What's that" ? Asked Grrr.
"Well, I was annoyed about that tire store...you know the one that tried to ripoff Gretta for the battery".
"Yeah?" Said Grrr.
"Yeah. So I went down there this morning to talk to the manager."
"Humm"..Said Grrr.
"Yeah. "humm?" Bob replied with a knowing look.
"The store is closed and the there is a "out of business" sign on the door."
"You don't say?" said Grrrr with an innocent look.
"Yep, and you know ole buddy, before the rain washed it away, I think I saw what looked a t-rex foot print in the mud."
"Humm, too bad it got washed away." replied Grrr...As he hosed off his right foot.
