So a blonde, a redhead, a ginger are talking. The red head says "I'll be the first red head to land on Mars." The ginger says well "I'll be the first ginger to land on Venus." The blonde says "well ill be the first one to land on the Sun" So the ginger says "well wont you just burn up" The blonde says "don't be stupid I'll go at night."
