some jokes and riddles

You're at a ballpark watching the game when a vendor comes by selling beers around the top of the third inning. As a safety requirement, most major league stadiums don't sell beer after the seventh inning. The vender yells,

"Last cold beer!!"

But the way the vendors say it leaves the fans but to only hear,

"Last CALL beer!!"

See what they did there?

A friend has two buddies who are both named Miles. Both smoke marijuana. What do you get when you put them together? 

Two Miles per hour on the highway.
